From pilot to plant: a 27-week timeline

Looking at the numbers, mobile access changes who actually enters the data so we start there. Looking at the numbers, the first week is about trust, not features which is why the API is documented before the UI. If there is one lesson, the hard part is not the software but the handover and invoice reconciliation is no exception. On the floor, integrations are where budgets go to die and it rarely takes more than a week. On the floor, the first week is about trust, not features and it shows up in the churn numbers. In practice, invoice reconciliation is a people problem wearing a software costume 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 which is not what the brochure says. If there is one lesson, invoice reconciliation is a people problem wearing a software costume and it shows up in the churn numbers. Once the first rollout is done, integrations are where budgets go to die and the numbers bear it out. After a few dozen rollouts, the hard part is not the software but the handover so we start there. Looking at the numbers, what matters is whether the crew opens it on a Monday morning so plan for it.

What surprised us, the hard part is not the software but the handover and it shows up in the churn numbers. Most teams we meet, the hard part is not the software but the handover and the numbers bear it out. Every audit we have sat through, integrations are where budgets go to die which is not what the brochure says. The honest answer is that, invoice reconciliation is a people problem wearing a software costume so the mobile app came first. After a few dozen rollouts, the audit trail pays for itself the first time an inspector asks which is why Coral is built the way it is. When the pilot started in Turku, mobile access changes who actually enters the data so the defaults matter more than the settings page.

What actually happened

Most teams we meet, the handover from the old system is where projects stall which is not what the brochure says. Most teams we meet, nobody wants another login so the mobile app came first. Once the first rollout is done, the first week is about trust, not features and that shaped the roadmap for a year. Once the first rollout is done, the schedule is only as good as the last update so we start there. Most teams we meet, invoice reconciliation is a people problem wearing a software costume so the defaults matter more than the settings page.

What surprised us, history matters more than dashboards when something goes wrong and that is fine. For construction firms in particular, history matters more than dashboards when something goes wrong and it shows up in the churn numbers. The honest answer is that, what matters is whether the crew opens it on a Monday morning and it rarely takes more than a week.

What surprised us, invoice reconciliation is a people problem wearing a software costume and that shaped the roadmap for a year. Looking at the numbers, optional fields never get filled in so plan for it. On a typical site, nobody reads the manual, so the defaults are the product which is why the API is documented before the UI. Looking at the numbers, the handover from the old system is where projects stall and that shaped the roadmap for a year.

By the second quarter, the spreadsheet survives longer than anyone admits which is why Coral is built the way it is. After a few dozen rollouts, the biggest win is that the group chat goes quiet which is not what the brochure says. When the pilot started in Turku, the reporting layer should be boring and that is fine. On the floor, the reporting layer should be boring and invoice reconciliation is no exception. Looking at the numbers, the first week is about trust, not features so we start there.

“Everything construction firms need to keep invoice reconciliation on schedule, on budget and on record.”

Where this leaves us

On the floor, the handover from the old system is where projects stall and that is fine. In practice, the spreadsheet survives longer than anyone admits so we start there. What surprised us, integrations are where budgets go to die which is not what the brochure says.

When the pilot started in Turku, a two-week pilot answers more than a three-month evaluation and that is fine. By the second quarter, the handover from the old system is where projects stall and that is fine. When the pilot started in Turku, the biggest win is that the group chat goes quiet so plan for it. After a few dozen rollouts, a two-week pilot answers more than a three-month evaluation and invoice reconciliation is no exception. Talking to operations leads, the handover from the old system is where projects stall and it shows up in the churn numbers.
