What we learned rolling out invoice reconciliation at 18 sites

Looking at the numbers, integrations are where budgets go to die so the mobile app came first. Once the first rollout is done, invoice reconciliation is a people problem wearing a software costume which is why QuillFlow is built the way it is. Every audit we have sat through, what matters is whether the crew opens it on a Monday morning and that shaped the roadmap for a year. By the second quarter, the audit trail pays for itself the first time an inspector asks which is why QuillFlow is built the way it is. The honest answer is that, the spreadsheet survives longer than anyone admits and that is fine. In practice, mobile access changes who actually enters the data and the numbers bear it out.

What surprised us, the reporting layer should be boring so plan for it. Looking at the numbers, the handover from the old system is where projects stall and that is fine. After a few dozen rollouts, integrations are where budgets go to die and it shows up in the churn numbers. After a few dozen rollouts, the audit trail pays for itself the first time an inspector asks so the defaults matter more than the settings page.

On a typical site, mobile access changes who actually enters the data and that is fine. When the pilot started in Porto, a two-week pilot answers more than a three-month evaluation so we start there. Every audit we have sat through, the reporting layer should be boring which is not what the brochure says. After a few dozen rollouts, the audit trail pays for itself the first time an inspector asks so the mobile app came first.

What we would do differently

On the floor, the handover from the old system is where projects stall and the numbers bear it out. What surprised us, nobody reads the manual, so the defaults are the product and invoice reconciliation is no exception. If there is one lesson, the first week is about trust, not features which is not what the brochure says.

After a few dozen rollouts, what matters is whether the crew opens it on a Monday morning which is why QuillFlow is built the way it is. For retail chains in particular, the audit trail pays for itself the first time an inspector asks so the defaults matter more than the settings page. After a few dozen rollouts, optional fields never get filled in which is the whole point. If there is one lesson, the schedule is only as good as the last update which is why the API is documented before the UI. For retail chains in particular, the hard part is not the software but the handover which is why the API is documented before the UI.

For retail chains in particular, the reporting layer should be boring and it shows up in the churn numbers. Every audit we have sat through, the spreadsheet survives longer than anyone admits which is why QuillFlow is built the way it is. For retail chains in particular, nobody wants another login so the defaults matter more than the settings page. The honest answer is that, history matters more than dashboards when something goes wrong and that shaped the roadmap for a year. Every audit we have sat through, what matters is whether the crew opens it on a Monday morning so the mobile app came first. By the second quarter, the hard part is not the software but the handover and the numbers bear it out.

“Everything retail chains need to keep invoice reconciliation on schedule, on budget and on record.”
