// Accounting integration
A2X and Cin7, with revenue and COGS posting once each.
Your marketplace payouts should match the bank. Your inventory costs should follow the stock. Fiskal sets up which system owns which entry, so your books and your channels agree.
See which system is posting what in your setup.
01 // The reality gap
Both tools are connected. The numbers still do not match.
You connected A2X. You connected Cin7. Both show as active.
Yet revenue looks high one month. Margin looks odd the next. Shopify says one thing. QuickBooks says another.
The integrations are connected, so the entries must be right.
Connected means data is moving. It does not mean each entry is posted by the right system, once, in the right period.
Most A2X and Cin7 problems are not tool problems. They are ownership problems.
02 // Proof
Recognized by Cin7 for connecting accounting and inventory.
Cin7 named Fiskal its Accounting Partner of the Year in 2025 and 2026. Cin7 pointed to Fiskal’s ability to connect accounting, inventory, and reporting.
Fiskal is also an A2X partner.

03 // What is actually happening
Two systems, one ledger, and a question nobody answered.
Amazon, Shopify, and other channels pay out in lump sums. Each deposit bundles sales, fees, refunds, and taxes. A2X breaks every payout into a summary and posts it to QuickBooks Online or Xero. That summary matches the deposit in your bank feed.
Cin7 does a different job. It tracks stock, landed costs, and the cost layers behind COGS. It can also post to the same ledger.
That is where it goes wrong. Two systems can post to one ledger. If nobody decides who posts what, both do.
Three patterns to check first
The Double Entry Trap
Cin7 posts a sales invoice. A2X posts the payout summary for the same orders. Revenue shows twice.
The Timing Gap
A2X posts sales by payout period. Cin7 posts COGS on its own schedule. When COGS posts before the sale does, margin is skewed until A2X catches up.
COGS posted twice
A2X can post COGS. Cin7 can post COGS. When both are on, cost is counted twice. In Xero, items with inventory tracking turned on can also create duplicate COGS entries.

05 // Operational cause, financial consequence
What the setup does to your financials
Posting settings look like admin. They decide what your P&L says.
- Cin7 still posts sales invoices alongside A2XRevenue is overstated. Cleanup becomes a month end job.
- Cin7 posts COGS before A2X posts the saleGross margin swings between periods.
- COGS is turned on in both A2X and Cin7Cost of goods sold is overstated. Margin is understated.
- Fees and refunds mapped to one catch all accountChannel margin disappears into a single line.
- Xero inventory tracking on for Cin7 itemsDuplicate COGS entries.
None of these show up as errors. They show up as numbers that almost make sense.
06 // Strategic impact
What it costs the people making decisions.
You cannot compare channels if fees and refunds blur together. Amazon and Shopify do not cost the same to sell on. A blended margin hides that.
You cannot trust gross margin if COGS timing moves around. Pricing and reorder decisions follow that number.
And your team keeps fixing it by hand at month end. That time has a cost too.
Set up correctly, A2X and Cin7 together give you channel by channel margins in QuickBooks or Xero. That is the point of connecting them.
07 // What Fiskal does
One owner for every entry.
Fiskal understands both sides. How Cin7 and A2X are configured. And what that does to the ledger.
Audit
We trace each type of entry to the system that posts it. We review your Cin7 posting settings, your A2X settings, your account mapping, and your Xero inventory tracking.
Align
We set the split. A2X owns revenue, fees, refunds, and taxes from your channels. Cin7 owns inventory and COGS. In Cin7 Core, that means sales invoice posting off and COGS posting on. In A2X, COGS is turned off. On Cin7 Omni, there are two valid patterns. We choose the one that fits how you cost inventory.
Govern
We document who owns what. We check posting timing at close. A settings change should not quietly bring the duplicates back.

- Payout match to the bank depositA2X
- Inventory adjustmentsCin7
- Landed costs and cost layersCin7

Fiskal does not replace A2X. A2X stays the tool for payouts. Fiskal makes sure it works with Cin7 and does not fight it.
Fiskal does not move to the next phase until the data in the current one is sound.
08 // 5 questions
A2X and Cin7, answered
Do I need both A2X and Cin7?
They do different jobs. Cin7 manages stock, costs, and inventory accounting. A2X reconciles marketplace payouts. Together they give you inventory control and clean channel accounting.
Which Cin7 settings need to change?
In Cin7 Core, turn off sales invoice posting and leave COGS posting on. Then turn off COGS in A2X. Cin7 Omni has two valid setups, depending on who posts COGS.
Does this work with Cin7 Omni?
Yes. Both A2X and Cin7 document setups for Omni.
Which accounting software does Fiskal support with A2X?
QuickBooks Online and Xero.
Why does my margin look wrong after setup?
Often it is timing. If Cin7 posts COGS more often than A2X posts sales, margin is skewed until the sale posts. Fiskal checks posting timing at close.
