01Before the connection

Fifty orders a day is fine.
Five hundred is a second job.

The work per order never falls; it only gets multiplied. The month you grow fastest is the month the books fall furthest behind.

Retail and wholesale land in the same feed

A tier-priced net-30 order and a full-price retail sale look identical in a spreadsheet. They are not the same money, and they are not the same day.

Collected tax sits in the account looking like revenue

$517 across three jurisdictions is in the bank right now. Spending it feels fine, right up until the filing date.

$517 · not yours

Nobody can say which category is carrying the store

Home goods and seasonal both sell. Only one of them is worth restocking, and the answer lives in a CSV somebody still has to build.

02What flows in

Five things arrive
with every order.

One read-only token, and this is the whole of what CashFish takes from the store.

DIRECTION OF TRAVELThe connection is read-only and one-way: BigCommerce data comes into CashFish, and CashFish never writes anything back to your store.

03The order that looked like $120

One order.
Six numbers.
Only one of them yours.

A single order, taken apart. The list price is the only number the dashboard shows you.

Fees, discounts and refunds are read per order. A wholesale order and a retail order stop averaging each other out, and the tax you collected stops looking like money you earned.

04What becomes visible

What that changes
at volume.

A month that closes itself

Orders arrive with their status, terms and adjustments intact — B2B net-30 invoices next to retail sales, refunds already applied.

Margins by category, not by gut feel

Revenue is mapped to the categories you defined, so you can see which product lines are pulling their weight.

Tax set aside before you spend it

Collected tax never masquerades as revenue — it is tracked as a liability from the moment the order syncs.

Forecasting in CashFish is built from this history — real orders, real fees, real receivables and recurring patterns. It produces estimates, not certainties, and it never claims to know what next quarter will do.

05How to begin

Two minutes in BigCommerce, one in CashFish.

Create a store API token

In your BigCommerce settings, create an API account with read-only scope for orders and products. It takes about two minutes.

Paste it into CashFish

Add the token under Integrations and the connection verifies in seconds. Works with any BigCommerce plan that includes API access — Standard through Enterprise.

Map categories and import

Link product categories to revenue lines, optionally pull in your order history, and let the live sync take over from there.

06Connects well with

Most stores are more than one channel.

ShopifyOrders, refunds and Shopify fees — private beta WooCommerceRead-only REST key, orders and gateway fees MagentoRead-only REST token, multi-store consolidation PayPalPayouts matched to the orders inside them

Store, payment and bank connections all sit on Growth and above, so a shop, a card processor and a business account can report into the same set of books. QuickBooks and Xero import one way into CashFish and are never written back to.
