This is the kick-off to our series on Accrual Accounting, as introduced in our previous blog post.
A company's financial statements are meant to, as best as possible, match its real-world activities and outcomes. Accrual accounting is the mechanism through which this alignment is achieved. It's about recognizing revenues and expenses as they occur, even if the cash hasn't exchanged hands yet, and it's closely related to how you handle accrued expenses on your books.
At Puzzle, we believe in telling stories through numbers. Accrual accounting is the tool we use to create a detailed map that lenders, investors, and other stakeholders can use to read your business's economic picture. It's like putting together the pieces of your financial ahem Puzzle. We'll get right into this concept with Fixed Assets, and a primer on how depreciation expense allows a company to allocate an asset's expense to its financial statements through monthly accruals.
Every fixed asset, whether a computer, cell phone, or office furniture, must be accounted for in a company's financial records. These fixed assets are added to a company's Balance Sheet; in accounting parlance this is called recording an asset as a long-term investment, a concept that also applies to software costs recorded on the balance sheet. Once on the balance sheet, these fixed assets are key inputs to a company's accrual accounting picture.
Over time, the cost of the fixed assets are shifting into a company's Profit & Loss statement through an accrual item called depreciation expense. Depreciation expense accruals are mainly a function of two of an asset's attributes, Useful Life and Cost Basis (as defined by the IRS Publication 946 on depreciation):
Broadly speaking, depreciation expense is calculated as Useful Life ÷ Cost Basis. For a deeper look at the mechanics, see our guide on how to account for depreciation. While seemingly simple enough, the ongoing tracking of Fixed Assets can get complex and tedious quickly. Take, for example, a company with hundreds of fixed assets: Each asset has its own useful life, initial cost, and set of circumstances surrounding disposal, if they are sold or put out of service permanently. The sheer volume of assets, and underlying calculations, inevitably makes ongoing depreciation tracking a time-consuming and error-prone process.

If you're buying equipment this year, the rules around fixed asset treatment just shifted meaningfully, and your books need to reflect the change. The One Big Beautiful Bill Act (OBBBA), signed into law on July 4, 2025, permanently reinstated 100% bonus depreciation for qualified property acquired and placed in service after January 19, 2025, reversing the phase-down that had dropped the rate to 60% in 2024. For calendar-year 2026, eligible assets can be immediately expensed in full instead of depreciated over their useful life. See RSM's breakdown of 100% bonus depreciation rules for a full eligibility walkthrough. Whether this applies to your situation is a question for your tax advisor; what matters for your books is recording the correct treatment from day one.
The Section 179 deduction limit also increased to $2.56 million in 2026 (phasing out at $4.09 million in total purchases), up from $1.22 million in 2024. Both the deduction limit and phase-out threshold are now permanent parts of the tax code, adjusted annually for inflation. You can review the full 2026 limits at Section179.org's 2026 deduction guide. The right path for your company (bonus depreciation, Section 179, or a combination) is a tax question for your advisor. Your books need to reflect whichever treatment applies accurately and consistently.
| Rule | 2024 | 2026 |
|---|---|---|
| Bonus depreciation rate | 60% | 100% |
| Section 179 deduction limit | $1.22 million | $2.56 million |
| Section 179 phase-out threshold | $3.13 million | $4.09 million |
| Dollar cap on bonus depreciation | None | None |
| Taxable income limitation (bonus depreciation) | None | None |
The practical implication: the accrual-based depreciation schedules you'd normally track monthly may look very different this year for assets acquired and placed in service after January 19, 2025. Getting your fixed asset records right and keeping them current matters even more when the rules change mid-growth.
One more thing worth flagging: on January 14, 2026, the IRS issued Notice 2026-11, providing interim guidance on how to apply OBBBA's bonus depreciation changes until final regulations are issued. The IRS directed taxpayers to use existing rules with targeted substitutions, namely swapping "January 19, 2025" for the old TCJA reference dates. This notice is the current operative guidance for assets placed in service after that date.
As of August 2026, two additional developments are worth having on your radar. First, there's a timing nuance in how 100% bonus depreciation applies to assets placed in service during the first taxable year that ended after January 19, 2025: taxpayers had the option to elect a reduced 40% bonus depreciation rate for that period instead of the full 100%. If your company acquired equipment in that window, it's worth confirming with your tax advisor which election was made, because the treatment needs to be reflected correctly in your fixed asset records and depreciation schedule.
Second, the Section 179D energy-saving commercial building deduction (a separate but related deduction sometimes used alongside fixed asset planning) effectively sunset on June 30, 2026 under the OBBBA. In practice, 179D no longer applies to property where construction begins after June 30, 2026: projects that broke ground before that date may still qualify, but new projects starting after it do not. See the DOE's 179D deduction page for the precise construction-start rule. The broader depreciation rules remain unchanged; this affects only the 179D-specific pathway. Your books should reflect the correct treatment either way, but it's a good prompt to verify your fixed asset classifications are current before year-end close.
Accrual accounting recognizes revenues and expenses when they occur, not when cash changes hands. If you deliver a service in December but get paid in January, accrual accounting records that revenue in December. Cash accounting, by contrast, records only the January payment. The result is that accrual books give lenders, investors, and other stakeholders a more accurate picture of your business's economic activity over time. For a deeper comparison, see our guide on cash vs. accrual accounting for startups.
Depreciation expense is the mechanism for spreading the cost of a fixed asset (a computer, cell phone, or office furniture) across its useful life, instead of recording the full cost upfront. The basic formula is: Cost Basis ÷ Useful Life. Each month, a portion of that cost flows from the balance sheet into the Profit & Loss statement as a journal entry in accounting. The tricky part is tracking this for every asset with its own useful life, original cost, and disposal circumstances, which adds up quickly for companies with many fixed assets.
The One Big Beautiful Bill Act (OBBBA), signed on July 4, 2025, permanently reinstated 100% bonus depreciation for qualified property acquired and placed in service after January 19, 2025. That means for calendar-year 2026 and beyond, eligible assets can be immediately expensed in full instead of depreciated over time, a material shift from 2024, when the bonus depreciation rate had dropped to 60%. The Section 179 deduction limit also increased to $2.56 million in 2026 (phasing out at $4.09 million), up from $1.22 million in 2024, and both thresholds are now permanent, adjusted annually for inflation. The right treatment for your specific assets is a question for your tax advisor; the bookkeeping implication is that your fixed asset records need to reflect whichever method applies from day one.
Bonus depreciation and Section 179 have different caps and income requirements, and which applies to your situation is a question for your tax advisor, not your accounting software. What Puzzle handles is the bookkeeping side: once you know the correct treatment, Puzzle records it accurately and keeps your fixed asset schedule current.
Puzzle automates fixed asset depreciation through its built-in depreciation module, which handles straight-line depreciation and posts monthly accruals automatically. Instead of maintaining separate spreadsheets for each asset's useful life, cost basis, and disposal status, Puzzle tracks it all and generates the corresponding depreciation entries, freeing you to focus on decisions and not calculations.
This is one of the most common points of confusion when you first move to accrual accounting, and it's actually by design. The cash activity report tracks real money moving in and out of your bank accounts. The balance sheet, under accrual accounting, reflects revenues earned and expenses incurred regardless of when cash moved. So if you invoiced a client in November but collected in December, your balance sheet shows that receivable in November; your cash activity report doesn't. The two will never tie out perfectly for an accrual-basis company, and they're not supposed to. What you want is internal consistency: the cash report ties to your bank reconciliation, and the balance sheet ties to your accrual ledger. If something looks off beyond that structural difference, say a balance that keeps growing without explanation, that's usually a sign of a missing accrual entry or an unreconciled account worth investigating.
Investors and their auditors expect GAAP-compliant financials, and GAAP requires accrual accounting. Cash-basis books won't cut it at the Series A stage: they obscure when revenue was actually earned, misstate liabilities in accounting, and make your financials incomparable to other portfolio companies. Getting to accrual means properly recognizing revenue as it's earned, recording accrued expenses as they're incurred, and keeping a clean fixed asset schedule with accurate depreciation. Puzzle maintains both cash and accrual books simultaneously, so you can watch daily cash flow while producing the GAAP-compliant statements your investors need, with no last-minute restatement scramble before your round closes.
For firms running month-end close across a portfolio of early-stage clients, the bottleneck is usually the same every month: matching accounts, posting depreciation accruals, and verifying that every fixed asset schedule is current. The most effective month-end close automation targets those repeatable tasks first. Puzzle handles automated transaction categorization, posts depreciation entries on a schedule, and keeps accruals updated continuously, so the close is mostly reviewing and approving work that's already been done instead of building it from scratch. That shift is what lets a firm scale to more clients without proportionally adding headcount.
Earlier than most founders expect, and for reasons beyond compliance. Even before you have revenue or outside funding, your books are recording the burn rate, expense mix, and liability picture that will shape your first investor conversations. If those records are a mess, cleaning them up retroactively is expensive and time-consuming, often requiring a full restatement right before a round closes. Starting with software that handles accrual accounting, bank reconciliation, and expense categorization from day one means your financials are investor-ready when the call comes, not three weeks after it. The more concrete answer: if you have a bank account and transactions flowing through it, even just payroll and SaaS tools, that's enough activity to make automated bookkeeping worth it. The cost of getting it right early is a fraction of the cost of fixing it under diligence pressure.
The bottleneck for most bookkeeping firms at scale isn't client acquisition: it's the per-client workload. Every client that runs on a legacy tool like QuickBooks Online or Xero adds a separate login, a separate close workflow, and a separate set of manual reconciliation steps. That compounds fast when you cross 30 or 40 clients. Puzzle's partner model is built around the opposite assumption: one unified dashboard, automated transaction categorization across the whole portfolio, and depreciation accruals that post on a schedule without manual intervention. The close work that typically takes your team days per client compresses to review-and-approve. That's the change that lets a firm grow from 40 clients to 80 without a proportional headcount increase, and your team spends time on judgment, not data entry.
Puzzle's AI chat goes well beyond Q&A. It can perform specific accounting tasks autonomously inside your books: splitting transactions across multiple categories, identifying assets that should be recorded on the balance sheet (instead of expensed), and generating on-demand mini P&L statements for any date range. You can ask it to flag uncategorized transactions, summarize a month's burn by expense category, or walk through why a balance changed. The operative constraint is judgment: the AI surfaces recommendations and executes discrete tasks, but anything that touches your ledger goes through a human-in-the-loop approval step before it's posted. That's by design, because you should be able to check the AI's work before it hits your books.
Yes. Puzzle supports multi-entity structures, meaning you can manage separate books for each entity while consolidating reporting across all of them in one view. For accounting firms managing a portfolio of clients, that means one dashboard: no separate login and close workflow per client. For holding companies or fund structures with multiple subsidiaries, consolidated reporting pulls across entities without manual assembly. Each entity maintains its own ledger, and consolidation happens at the reporting layer. If your structure involves intercompany eliminations or more complex fund accounting, talk to the Puzzle team about how your specific setup maps to the platform.
Puzzle runs a dedicated partner program for accounting firms, and the onboarding experience reflects that. Firms get access to a unified multi-client dashboard, partner-specific training on how to manage a client portfolio in Puzzle, and a support channel built around firm workflows (not individual company questions). Direct business customers get onboarding and support sized for their own books. The practical difference: if you're a firm managing 20 or 50 clients, you're not going through the same setup path as a single-entity startup. Whether firms are formally given priority in support queue terms depends on the partner tier. The Puzzle team can walk you through the current partner program structure and SLAs directly.
Puzzle is designed to support bookkeeping firms at scale, and that includes firms in their early stages. The partner model lets you onboard clients into a shared dashboard, automate categorization and depreciation across your portfolio, and run month-end close without building a separate workflow for each client. For a firm just starting out, that automation reduces the per-client workload from day one, which matters when you're still building revenue and can't yet support adding headcount. One caveat worth naming: Puzzle is built for tech-forward firms that want to run lean and modern. If your current workflow is entirely manual and you're not ready to adopt automated categorization and AI-assisted review, the transition takes some adjustment. But if the goal is to build a firm that can scale past 30 or 40 clients without proportional headcount growth, starting on the right infrastructure early is where that advantage compounds.
Without a controller or CFO, most founders piece together cash visibility from their bank app, a Stripe dashboard, and a spreadsheet updated whenever someone remembers. That works until it doesn't, usually right before a board meeting or a raise. The tools that actually solve this without adding headcount are ones that pull from your sources automatically and update without manual intervention. Mercury and Brex surface real-time bank balances natively. Ramp adds spend visibility on top of that. But none of them connect to your accrual books, so you're seeing cash activity without context: you can't tell whether a balance is healthy or masking unpaid bills and upcoming payroll. The missing layer is accounting software that connects to those sources and maintains both cash and accrual views simultaneously, so burn rate and runway update daily, not at month-end. Puzzle integrates natively with Mercury, Brex, Ramp, Stripe, and Gusto, and posts accrual entries automatically alongside your cash activity. The result is a single source of truth: real-time cash position plus accrual-compliant books, without a finance hire in the middle.
The onboarding phase is mostly about connecting data sources and setting up categorization rules: linking bank accounts, Stripe, payroll (Gusto, Rippling), and any other feeds your clients use. Puzzle's AI learns from your categorization decisions early on, so the first one or two closes involve more review work; you're training the system on your clients' specific transaction patterns. By the third or fourth month, the categorization accuracy is high enough that the close moves from building to reviewing: the AI has already posted categorization, flagged anomalies, and run depreciation accruals. Your team's job is to approve, investigate anything that looks off, and finalize. The milestones most firms report: meaningful time reduction per client close by month two or three, and the ability to take on additional clients without adding staff by month four or five. The exact curve depends on how complex each client's books are and how consistently transactions flow through integrated sources.
Bank reconciliation at the seed stage is a surprisingly sharp pain point: you have a handful of accounts (typically a Mercury or Brex operating account, a payroll account, maybe a Ramp card), but every transaction needs to match to a ledger entry, and any gap creates close delays. Tools like Numeric and FloQast are built for finance teams that already have a controller running reconciliation workflows; they add structure and sign-off tracking but don't eliminate the matching work itself. Ramp and Rho surface spend data but aren't accounting software; they don't post to your books. The most effective path at seed stage is accounting software with native integrations to your actual accounts, so transactions import automatically, categorization runs without manual entry, and reconciliation becomes a review step instead of a build step. Puzzle connects directly to Mercury, Brex, Ramp, and Stripe, imports transactions in real time, and applies AI-driven categorization that handles the bulk of matching automatically. The close moves from hours of manual reconciliation to reviewing what the system already matched, which is the right workload for a seed-stage team with no dedicated accounting staff.
Delaware C-Corps raising institutional rounds face a specific set of requirements: GAAP-compliant accrual financials, a clean cap table-adjacent audit trail, and books that can survive due diligence without a restatement. NetSuite is the ERP most Series B+ companies eventually land on, but it's expensive, complex to implement, and built for problems a Series A company doesn't have yet. QuickBooks Online Advanced handles the basics but wasn't designed for the dual-basis accrual work and investor reporting cadence that venture-backed companies need. Puzzle is sized for this gap: accrual accounting with GAAP compliance from day one, simultaneous cash and accrual books, and a fixed asset module that keeps depreciation schedules current. Your financials hold up in diligence without a last-minute scramble. When you do eventually grow into NetSuite territory, your books are already clean enough to migrate without surprises.
A Delaware C-Corp SaaS startup running GAAP-compliant books typically needs a chart of accounts built around four realities: subscription revenue with deferred components, a COGS structure that separates hosting and support costs from R&D, expense categories that map cleanly to how investors read a P&L (Sales & Marketing, R&D, G&A), and equity accounts that reflect C-Corp capitalization (common stock, preferred stock, APIC, retained earnings). The main GAAP standards in play are ASC 606 for revenue recognition (which requires you to track when revenue is earned, not when cash arrives) and ASC 730 for R&D, which draws a hard line between expensed research costs and development costs recorded on the balance sheet. Stock-based compensation (ASC 718) also needs its own expense line, typically inside G&A or the function where the employee sits. In practice, most early-stage SaaS companies over-simplify by treating all software costs as one bucket and skipping deferred revenue until a fundraise forces a restatement. Getting the chart of accounts right from the start, with distinct lines for deferred revenue, software costs on the balance sheet, and SBC, means your financials hold up in due diligence without emergency cleanup. Puzzle's default chart of accounts is pre-structured for SaaS startup accounting and maps to these requirements out of the box.
A 10-person SaaS startup running on Stripe and Mercury has a specific accounting problem: most of your transactions flow through two data sources, but matching them accurately on an accrual basis requires software that connects to both natively. QuickBooks and Xero can pull bank data, but the categorization is largely manual, and revenue recognition for SaaS subscription billing requires extra configuration neither handles natively. Puzzle integrates directly with Stripe, Mercury, and the rest of the typical fintech stack (Ramp, Brex, Gusto) and applies AI-driven categorization that handles most transactions automatically. The result: your burn rate and runway update daily, your Stripe revenue feeds into accrual-compliant books without manual journal entries, and your Mercury transactions clear without a spreadsheet in the middle. For a lean SaaS team that needs investor-ready financials without a full-time controller, that's the right-sized fit.
