For Shopify store owners

Make Shopify, stock, shipping, and customer tools work together.

Checkout is the middle of the job, not the end. This is the work that keeps stock, deliveries and your numbers agreeing with each other afterwards.

Carrtel connects Shopify to the other systems a store runs on, such as inventory and fulfilment workflows, as custom work. Each job is quoted after a discovery call, with a written scope and a firm price before it starts, and changes are made on a copy and shown to you before they go live.

Is this for me?

Four problems that all look like bad service.

None of these are problems with how the store looks, and none of them show up in a design review. They happen in the gaps between systems.

The order that shipped twice

One system was told the order went out and the other was not, so a second parcel goes out and the profit on the sale goes with it.

The tracking nobody sent

It shipped, but the message to the customer quietly failed. They find out by emailing to ask, and a delivered order becomes a support ticket.

Stock that disagrees with itself

The store says two left, the shelf says none, and you find out when someone tries to pack it instead of at checkout.

Numbers that will not add up

Payouts, refunds and fees that need a spreadsheet and an afternoon before anyone can say what the month actually was.

Interactive example

Follow an order from checkout to payout.

Pick a scenario and make the calls a merchant would: a stock count that disagrees with the shelf, a message that failed to send, a refund and the payout that follows. Watch the stock, the customer's messages and the ledger keep up.

One shirt from one location. Stock sits with a 3PL, the company that stores and ships for you, and one message fails on the way.

What it covers

One piece of work, in three parts.

Most stores need one of these. Some need all three. They are quoted together so you are not buying the same discovery twice.

01

Connect your tools

Shopify talking to the other things you already pay for — your accounting software, your email and messaging tools, your booking or helpdesk system, and the spreadsheet somebody still maintains.

What it helps with

  • The same information stops being typed in twice
  • A customer looks the same in every system
  • When something fails, you hear about it instead of a customer
How the connections are built
02

Orders, inventory & shipping

Keeping stock counts and delivery information accurate between Shopify and whoever picks, packs and ships — your own warehouse, or a 3PL, the company that stores and ships your products for you.

What it helps with

  • Fewer double-shipped and fewer quietly stuck orders
  • Stock counts that match what is actually on the shelf
  • Customers told where their parcel is without asking
Orders, inventory & shipping
03

Sales, payouts & refund checks

Checking that your sales, refunds, fees, tax and payouts agree with the orders behind them, and finding the point where they stopped agreeing.

What it helps with

  • Month-end stops being an investigation
  • Discounts that were costing more than intended get found
  • Refunds that never landed anywhere show up as a number
Sales, payouts & refund checks

What it costs

We look before we price.

Small, well-defined jobs are $250–$750. Larger work is quoted after a short call, because the price depends on which systems are involved. You get a written scope and a firm price before anything starts.

Questions

Shopify integrations: common questions

Usually not. Most of it is joining up systems you already run, set up for the way your business actually works. Where an app already does the job well, we will tell you to use the app.

Where words are involved — drafting a reply to a customer from their order history, sorting an incoming message, summarising a long thread. The connecting and checking is ordinary engineering, and calling it AI would be marketing rather than a description.

Shopify plus whatever sits behind it: a warehouse or a 3PL, an accounting package, a helpdesk, a spreadsheet somebody maintains. Part of the first conversation is finding out what can be connected cleanly, and saying plainly when something cannot.

No. The checks make sure the systems produce numbers that agree with each other, so your accountant is working on something reliable. The accounting is still theirs.

Small, well-defined jobs are $250–$750. Larger work is quoted after a short discovery call, with a written scope and a firm price before anything starts. Ongoing monthly help starts at $149 a month.
