COPA Accounting runs 70 to 80 e-commerce clients with manual uploads banned, on one piece of arithmetic: an hour of staff time at £25 against a connected channel at £15 a month.
Key Takeaways from this Post
An hour of staff time at £25 against a connected channel at £15 makes the manual route the expensive one.
Client size makes no difference, because the process is identical, and twenty manual clients would cost nearly a week each month.
With every ecommerce client on Link My Books, COPA takes on more clients per manager without adding headcount.







Every firm with ecommerce clients eventually faces the same small request: "Can't I just send you the sales report?" COPA Accounting's answer is now a flat no, and the arithmetic behind that answer is worth any practice manager's attention.
COPA Accounting is a UK digital-first firm working with businesses that operate mainly online: ecommerce brands, SaaS companies and agencies. Around half its client base is ecommerce, roughly 70 to 80 clients, and every one of them runs on Link My Books. Co-founder Jordan Cowsill has been with the tool for five or six years, since the firm started.
That start date matters. COPA never had a manual era to escape.
A firm that never did it by hand
Jordan can only describe the manual alternative as a hypothetical, and he does not rate it. Pulling sales reports from the platforms and keying them in "would be an absolute nightmare... I think, yeah, it'd just be carnage, really."
Having used connected software at previous employers, putting it at the centre of the new firm was automatic. "When we founded COPA Accounting, it was just natural to go ahead and get that." The moment of conviction came with the first Amazon data: "As soon as we got e-commerce clients and we looked at the data from Amazon, you think, we need something to help us out here, basically."
Trust was earned the unglamorous way. The support team was strong early on, the firm kept a keen eye on the integration and the tax setup, "and after a couple of months and a couple of years of it being correct, that's when you start to build the trust with the software." He is careful to note the team still watches any new tool closely; that scrutiny is the job.
His shorthand for the product is the plainest description any partner has given it: "Automated sales data extraction software. It just automatically extracts the sales data. It's as simple as that, really."
The onboarding process, proposal to compliance
For a firm running this many ecommerce clients, the process is deliberately uneventful.
At proposal. Link My Books is written into the proposal, priced per sales channel, and it is compulsory.
At setup. The account is created, the client gets an invite, their channels are connected, and the team does the account and tax mapping, importing into Xero from the date they choose.
Ongoing. The import is checked at whatever compliance task comes next, monthly bookkeeping, management accounts or the quarterly VAT return, "and then it'll naturally just flow through into the accounts and whatever we're preparing at the time."
If ten new ecommerce clients arrived tomorrow, all ten would go straight on. "No questions asked... that's how we're working at the moment."
Why manual uploads became a hard no
The policy used to be softer. A client selling a little through eBay would ask to skip the channel fee and send a report instead, and the firm, trying to be cost-effective for clients, would say yes.
"But it's never as simple as that. And if you end up with 20 clients in that scenario, then that's 20 hours per month lost. That's nearly a week of some staff member's time."
The arithmetic that ended it is the one he now puts to clients directly: a manual sales invoice is an hour of staff time charged at £25, against a connected channel at £15 a month. "So it just makes sense just to connect Link My Books... now it's very black and white. No, we will not be uploading anything manually."
The volume of the client's sales does not change the workload, which is why small sellers get no exemption. "It doesn't matter if it's a small amount. The data that we still need to put on and the process that we go through is still the same."
The only genuine exception is the handful of lesser-known platforms with no connection available, which the firm handles as the rare case rather than the rule.
What the firm gets back
On the reported average of five hours saved per client per month, Jordan finds the number credible from his own workings: an Amazon.co.uk report alone could take an hour, "and then if you're selling across Europe and eBay and stuff like that, yeah, I think that's entirely feasible."
Where does the time go? Not into spare capacity. "It just basically means that you can take on more clients per client manager, per assistant, which means the time and then the profitability and efficiency of the business all just improves."
The bigger effect is on what the firm is willing to sell at all. Without the automation, he says, monthly ecommerce work "is probably something we won't touch." With it, a market that makes up half the client base opened up, and he rates it a valuable half: "young, hungry entrepreneurs" who go on to need startups, holding companies and SPVs served, "so we can add a lot of value and generate a lot of fees sort of long term by working with them."
His summary of the steady state is deliberately unglamorous.
"When Link My Books is running as it should do, then it's just one less problem for us to have. And that might sound trivial, but that's really important, that we can just trust something to run in the background and not have issues."
Where to start
COPA's model is the policy, not the tooling alone: make the connection part of the proposal, price the manual alternative honestly, and stop absorbing hours the software removes for £15 a month.
Link My Books breaks every settlement into sales, refunds, fees and taxes and posts a clean summary to Xero or QuickBooks that reconciles against the bank deposit. Fourteen days, no card required, and a setup call with one of the in-house accountants.

Frequently asked questions
How should an accounting firm onboard ecommerce clients?
COPA Accounting's process: the software is named and priced in the proposal, the client's sales channels are connected at setup, the firm does the account and tax mapping, and the import is verified at the next compliance task. From there it flows into whatever the team is preparing.
Should firms accept manual sales reports from small ecommerce clients?
COPA stopped. A manual sales invoice costs an hour of staff time regardless of sales volume, and twenty clients on that basis cost the firm nearly a week of someone's month. Its rule now: if a connection exists for the channel, the client connects it.
How long does it take to trust the automation?
Jordan's answer is months to years, and deliberately so. The team watched the integration and tax setup closely at the start, and confidence came from the output being repeatedly correct, the same scrutiny the firm applies to any new tool.
How much time does automation save per ecommerce client?
Jordan finds the reported average of five hours per client per month "entirely feasible", noting a single Amazon.co.uk report could take an hour before European channels and eBay are added. The saving shows up as more clients per client manager rather than idle time.
Does it change which clients a firm can take on?
For COPA, decisively. Without automation, monthly ecommerce work is something the firm "probably wouldn't touch". With it, ecommerce is half the client base, and a route to long-term work with founders who go on to need startups, holding companies and SPVs looked after.
