TLDR

Plan a structured 30-day trial to avoid years of manual work and missed profits

Look for early warning signs like slow onboarding, poor reconciliation, and a lack of detailed reporting

Map your business complexity to accounting requirements before evaluating any provider

Use a scorecard with benchmarks to objectively assess provider performance

Test automation, support, and reporting to ensure long-term fit

The first 30 days with Amazon accounting services reveal everything.

Do they understand settlement reports? Can they map FBA fees correctly? Do they catch reimbursement opportunities or miss them entirely?

Most sellers sign contracts, hand over access, and wait months before realizing their accountant is categorizing fees incorrectly or delivering financials that do not match reality.

By then, fixing accumulated errors takes more time than switching providers. The first month is your evaluation window.

Watch for specific signals that separate Amazon experts from generalists guessing their way through marketplace accounting.

In this guide, you will learn what to monitor during the first 30 days, which red flags require immediate attention, and how to course-correct before small mistakes become expensive problems.

The 30-day window that determines your next 3 years

Your first month with a new Amazon accounting service sets the tone for your financial clarity and operational efficiency.

This is the period when your provider is most responsive, your team is focused on setup, and you have not yet built workarounds or locked data into their system.

Most sellers skip a structured trial and pay the price: lost time, inaccurate books, and missed insights that can take months to fix. Sellers who do not validate early often spend months cleaning up errors or switching later.

A structured trial is your best risk-mitigation tool.

Leading accounting automation platforms like Webgility enable rapid onboarding and immediate visibility, raising the bar for what sellers should expect.

Now that you know what is at stake, let us identify the early warning signs to watch for.

7 warning signs your Amazon accounting service is already failing you

If you spot these red flags during your trial, your provider is falling short. Act immediately rather than hoping things improve.

1. Onboarding takes longer than 5 business days

Your provider should connect Amazon Seller Central, authenticate your accounting system, and produce your first reconciliation within five days. Delays signal weak processes or resource constraints.

2. First Amazon sync shows payout/ledger mismatches

Pull your most recent settlement report. The sync should reconcile exactly to your accounting ledger. Gaps mean weak integration or flawed fee mapping.

3. Fee mapping is generic (cannot see FBA, referral, ad fees separately)

You need itemized visibility: referral fees, FBA charges, advertising costs, and subscriptions as separate line items. Generic Amazon fees entries hide margin leaks.

4. Inventory does not sync across channels within 1 hour

Update a product quantity in one store. It should appear in other channels and accounting within 60 minutes. Longer delays increase overselling risk.

5. Support response to a ticket >48 hours

Send a test ticket in week one. Best-in-class providers respond within 24 hours. Anything over 48 hours predicts future support failures.

6. Reports only show total revenue (no channel or SKU breakdown)

Your first report should include sales by channel, SKU-level margins, and detailed fee breakdowns. Total-only reporting provides zero actionable insights.

7. Manual reconciliation is still required

If you are still spot-checking or adjusting entries by hand, the provider has not automated reconciliation. True automation means zero manual work.

Now that you know what to avoid, let us define what success looks like for your business.

Map your Amazon complexity to accounting requirements

Your trial should be measured against the realities of your business. Accounting needs scale directly with business complexity.

Before evaluating any provider, make note of your:

SKU count: Managing 50 products is very different from managing 5,000. Larger catalogs require deeper reporting and accounting automation
Channel mix: Amazon-only sellers have simpler needs than those selling across Amazon, Shopify, and other platforms
Order volume: High-volume sellers (10,000+ orders/month) need robust automation and real-time sync
Fee complexity: Simple referral fees are easier to track than FBA, advertising, promotions, and international VAT

These factors drive your requirements for Amazon accounting services. For example, multi-channel sellers must have SKU-level sync, while high-volume sellers must automate Amazon reconciliation to avoid bottlenecks.

Set 2-3 measurable trial goals based on your business:

Reconcile last month’s Amazon settlement in under 1 hour, with zero manual adjustments
Get SKU-level margin reports for your top 20 products
Receive support responses within 24 hours

Once your goals are clear, use a structured scorecard to track your provider’s real-world performance.

The evaluation scorecard top sellers use (with benchmarks)

Track your provider across these five criteria. Use industry benchmarks to define “excellent,” “good,” and “concerning.”

Criteria	Excellent	Good	Concerning
Onboarding speed	3-5 days	6-10 days	11+ days
Data accuracy	100% payout match	<1% error	>1% error
Reporting clarity	SKU/channel-level	Customizable	Totals only
Support responsiveness	<24 hours	<48 hours	>48 hours
Ease of use	Self-explanatory	1 hour to learn	Training required

Webgility customers save up to 90% of time on reconciliation and close books 3x faster. Use these metrics as your “excellent” benchmark.

Now, let us put your provider to the test. Here is how to run the key technical checks.

Run these 5 tests to expose automation gaps

A real Amazon accounting service passes these five tests without manual work or delays.

Payout reconciliation: Upload last month’s Amazon settlement and check for an exact match with your ledger. Every dollar should be accounted for. If you need to adjust entries by hand, automation is lacking.
Fee breakdown: Ensure FBA, referral, and ad fees are itemized in your accounting. If all fees are bundled, you cannot track true margins. Amazon referral fees vary by category, with some categories charging up to 45%.
Inventory sync: Change a SKU in Shopify or another channel. Confirm the update appears in Amazon and your accounting system within 1 hour. Delays increase overselling risk.
Refund handling: Process a test refund. Confirm the system creates an automatic credit memo and adjusts revenue and inventory without manual steps.
Error handling: Intentionally create a mapping error (e.g., assign an order to the wrong product). The system should flag the issue and guide you to resolution.

Webgility automates these checks and flags issues instantly. If you are still doing manual work, it is time to reconsider.

Technical fit is only half the story. Now, test the human side: support and communication.

3 support scenarios that reveal provider quality

Test support before you need it in a crisis. Run these three scenarios:

Submit a ticket for a missing Amazon transaction: Track time to first response and resolution. Best-in-class providers respond in under 24 hours with clear, actionable answers.
Ask for a custom report: Request a report showing profitability by channel, excluding ad spend. Assess willingness and expertise.
Escalate a technical error: Report a sync or mapping issue. See if you receive a real solution or just a generic reply.

Next, review the actual deliverables. Are your reports actionable, or just data dumps?

Reviewing deliverables: Are reports and insights actionable?

Actionable reporting means you know your margins, fees, and inventory by channel and SKU. A strong Amazon accounting service dashboard or report should include:

Revenue by channel (Amazon, Shopify, etc)
SKU-level margin table (revenue, COGS, fees, net profit)
Fee breakdown (pie chart or table)
Payout reconciliation (line-item detail)
Inventory aging or turnover

If your provider’s reports lack these elements, ask why missing insights mean missed profits. Webgility’s dashboards include these by default, so use them as your benchmark.

Armed with your scorecard and deliverables, here is how to make your final decision.

Making your decision and next steps

Use your scorecard to decide; do not let inertia trap you with a poor provider. Tally your results and look for patterns:

If you have 4-5 “excellent” scores, commit with confidence
If you have 2 or more “concerning” scores, escalate, request a remediation plan, or prepare to switch

For escalation, clarify the gap, request a timeline, and escalate to a success manager if needed.

Here is how a best-in-class provider, like Webgility, addresses every evaluation point.

Frequently asked questions (FAQs)

What is the minimum I should expect from a trial?

You should expect full access to core features, the ability to connect your Amazon account, and support for importing at least one month of historical data. The provider should deliver onboarding and reconciliation within five business days.

How can I test if my provider is truly automating reconciliation?

Upload your latest Amazon settlement report and check if every order, fee, and refund is matched automatically in your accounting system. Manual adjustments mean automation is incomplete.

What are the signs I should switch before the trial ends?

If onboarding is delayed, books do not reconcile, reports lack SKU/channel detail, or support is slow, these are clear signs to switch.

Does Webgility support multi-channel sellers or only Amazon?

Webgility supports Amazon, Shopify, eBay, Walmart, and more, plus direct integrations with QuickBooks, Xero, and POS systems.
