The five seams where work gets retyped

Nobody decided to type the same address four times. It accumulated, one reasonable decision at a time.

The short answer

The five seams are the call into the job record, the job record into the calendar, the finished job into the invoice, the invoice into the books, and any of those into a customer message. Each one exists because two systems were bought at different times for different reasons. Finding them by name is most of the work, because a seam you can point at is a seam somebody can close.

Why seams form

Every one of them started as a good decision. You bought scheduling software because the paper diary stopped working. You bought accounting software because tax time was awful. Neither purchase was wrong and neither vendor was thinking about the other one.

The person who joins them is the seam. That is not a failure of the person or the software. It is the predictable result of buying tools one problem at a time, which is the only way a small business can afford to buy them.

The five, in the order a job meets them

Seam What gets typed twice
1 Call into job record Name, number, address, what is wrong
2 Job record into calendar Time, duration, who is going, address again
3 Finished job into invoice Parts, hours, the note about what changed
4 Invoice into the books Amount, date, category, customer again
5 Any of those into a message Everything, rewritten as a sentence

The address appears in three of the five. That is why a transposed house number is the classic expensive error: it gets copied forward before anybody notices.

Which seam to close first

Not the one that takes longest. Close the one where an error costs the most, which is almost always seam one, because everything downstream inherits whatever was typed there. A wrong number at the first seam is not a typo, it is a job you cannot deliver and a customer you cannot reach to say so.

Seam four is the tempting one because it is the most tedious, and it is usually the wrong place to start: the errors there are caught by reconciliation, which means they are annoying rather than costly.

What closing one actually means

Two systems that already talk to each other need connecting rather than replacing, which is the cheapest version and the one worth checking for first. Where they cannot talk, the job is to make the entry happen once and flow, rather than to make a person faster at doing it twice.

Data entry covers the mechanics of that, and the repeat-work model puts an hourly cost against the seams once you have found them. If you have not counted yet, the one-week tally is the place to start rather than here.

Frequently asked questions

Is buying one system that does everything the answer?

Sometimes, and it is worth pricing. The catch is that replacing four working tools with one is a migration, and migrations fail in ways that closing a seam does not.

What if the retyping is only a few minutes each time?

It usually is. The cost is not the minutes, it is the error rate and the interruption. Both scale with the number of seams rather than the time each one takes.

Can I close a seam without changing software?

Often, yes. Most of these are a matter of one system reading what another already knows. That is cheaper than either replacing a tool or hiring somebody to bridge it.
