You manage dozens of small-business clients. Each one has different revenue structures, different sales tax obligations, and different transaction patterns. You spend hours every month reorganizing their data, asking them for missing receipts, and manually calculating their sales tax liability before you can even start the real accounting work. The bottleneck isn’t your expertise — it’s the admin work before you can apply it. Accumulator is built to clear that bottleneck by automating the categorization and sales tax calculation work that eats your time without adding value to your relationship with the client.
Does this sound like you? You’re spending billable hours on data entry instead of advisory work. See how the platform handles the categorization for you — free for your first client’s first period, no credit card.
Does this apply to your business in Florida?
Yes, if you serve small Florida businesses with revenue between $50K and $500K that file sales tax returns. The Florida Department of Revenue requires all sellers of taxable goods and certain services to file sales tax returns, typically by the 20th of the month following the reporting period. If your clients file the DR-15 form (Florida’s sales tax return), managing their transaction data accurately is non-negotiable — and it’s where most of the manual work happens.
How the rate works
Florida’s sales tax structure is straightforward at the state level: a 6% state rate applies to taxable sales. On top of that sits a county surtax that varies by county where the transaction occurs. The combined rate you’ll see in your clients’ data depends on their location — a client in one county pays a different effective rate than a client fifteen miles away in the next county. Rather than memorizing each county’s rate, you direct your clients to floridarevenue.com or use their sales tax rate calculator to confirm the exact combined percentage for their location. This matters because a misfiled rate can trigger a correction down the line.
The key for CPAs managing a portfolio: you need a system that automatically applies the correct rate based on where each transaction occurred, not one where you manually enter rates for each client each month. That’s where automation saves you the most time.
How to file step by step
The DR-15 is Florida’s monthly sales tax return. Here’s the process your clients face, and where Accumulator intervenes:
Step 1: Gather transaction data. Your client (or you on their behalf) collects all sales and expense records for the month. This is where most CPAs spend the most time — requesting missing data, chasing down receipts, organizing a chaos of bank feeds and cash sales.
Step 2: Categorize and apply the tax rate. Each transaction must be classified as taxable or non-taxable. Florida’s rule is simple: tangible personal property is taxable unless specifically exempt; services are not taxable unless listed in Florida Statute 212. Once classified, the correct sales tax rate (6% state + county surtax) is applied to taxable sales. Accumulator automates this categorization and rate application based on your client’s business type and transaction data, producing a ready-to-review report that you verify before filing.
Step 3: Complete the DR-15 form. The DR-15 asks for total sales, taxable sales, and sales tax collected. You pull those figures from your categorized transaction report, enter them on the form (either on floridarevenue.com or via a tax software integration), and file. The filing deadline is the 20th of the month following the reporting period.
Step 4: Keep records. Your client must keep all supporting documentation — invoices, receipts, exemption certificates — for at least five years. Accumulator stores the categorized data and audit trail so you can pull those records if the Florida Department of Revenue requests them.
The workflow is the same for every client. The difference: Accumulator handles Steps 1 and 2 automatically. You handle Steps 3 and 4 — the decisions that require your judgment and license. This is how you scale your CPA practice without hiring more junior staff to do data entry.
Common mistakes
Mistake 1: Misclassifying services as taxable. A client who provides consulting, bookkeeping, or repair labor thinks those services are taxable in Florida because they saw another state tax them. They’re not — unless the service is specifically listed in Statute 212. The fix: confirm the service type in Accumulator and update the categorization rule once. From then on, similar transactions auto-categorize correctly. No manual adjustment each month.
Mistake 2: Using the wrong county rate for a multi-location client. Your client makes sales in Miami-Dade and Broward counties in the same month. You enter one combined rate for all transactions instead of applying the rate that matches where each sale happened. The consequence: the DR-15 is either overstated or understated, and you look like you missed it on review. The fix: confirm each client’s primary location and any secondary locations upfront in Accumulator, then let the system apply the rate based on the transaction location (if available in the data) or the client’s registered address if not.
Mistake 3: Forgetting exemption certificates. Your client made a sale to another business that provided an exemption certificate, so that sale isn’t taxable. But the transaction was coded as taxable in your first pass, and you didn’t ask your client for the certificate. The consequence: you file a return that includes taxable sales that should have been exempt, and your client pays tax they shouldn’t owe. The fix: during your monthly review conversation, ask your client about any bulk sales to other businesses. If they exist, ask for the exemption certificates and re-categorize those transactions as exempt before finalizing the report.
Mistake 4: Timing — recording the sale in the wrong month. Your client made a sale on June 28 but didn’t deposit the payment until July 5. You recorded it in July because the money arrived in July. Sales tax is due on the month the sale occurred, not the month you’re paid. The consequence: the June return is understated, the July return is overstated, and it looks like you didn’t know the accrual rule. The fix: use the transaction date from the invoice or receipt, not the deposit date, when you import data into Accumulator.
Frequently Asked Questions
1. Does Accumulator replace my CPA work?
No. Accumulator organizes and categorizes your clients’ transaction data, then produces a report ready for your review. You make the final decisions about exemptions, service classifications, and multi-state transactions. The software removes the data-entry bottleneck so you can focus on analysis and advice.
2. Can I use Accumulator if my clients have multiple business types?
Yes. You set up categorization rules by business type — one set for a consulting firm, another for a cleaning company, another for a retail shop. Accumulator applies the right rules to the right client each month. If a client’s business changes, you update the rules once.
3. How do I handle clients in multiple states?
Accumulator is built for Florida small businesses, so it applies Florida rates and rules automatically. If your client has multi-state sales, you’ll manage the out-of-state filing separately. The Florida portion is handled by the system; you review and file the DR-15 as usual.
4. What if a client’s data has errors or missing transactions?
Accumulator flags missing or inconsistent data during import, so you see the gaps before you review the report. You ask your client to provide the missing records, re-import, and the categorization updates automatically. No re-work required.
5. Does Accumulator integrate with my existing tax software?
Accumulator produces reports that export to PDF or CSV, so you can move the categorized data into your tax software or spreadsheet. The system is designed to reduce manual entry, not lock you into a new workflow.

Accumulator handles the transaction categorization and sales tax calculation for your Florida clients so you don’t. The result: you file more clients’ returns each month without more hours, your clients get faster turnaround, and you spend your time on strategy instead of spreadsheets. That’s how you grow a practice profitably. Start with Outsourcing Processing’s affordable membership for one client, test the workflow, then scale.
