Can I automate data entry between my systems?
Almost always, and it is usually the fastest payback available. Re-typing the same customer into a second system is pure cost with a defect rate attached, and it is exactly the kind of task that automates cleanly because the trigger, rule, and output are all obvious.
Before wiring it, settle which system owns each field. Two systems both believing they own the phone number will overwrite each other forever. The discipline is a field-ownership map: for every piece of shared data, one system is the source of truth and the others receive it, read-only. This sounds bureaucratic and takes an afternoon, and it is the difference between a sync that people trust and one that mysteriously reverts corrections — the classic symptom being a rep who fixes a phone number and finds the old one back the next morning.
Clean the existing data first or you will automate the duplicates. Deduplication is unglamorous and it determines whether anyone trusts the result. This means matching records across systems before the sync starts — usually on email or phone rather than on names, which never match exactly — merging what should be one record, and deciding what to do with the conflicts where the two systems disagree today. Skipping this step does not avoid the work; it converts it into a permanent background hum of 'which record is real?'
The mapping is where the actual engineering lives. Fields rarely correspond one-to-one: one system's freetext province meets another's picklist, dates arrive in two formats, one record on one side is two on the other, and required fields on the destination have no source. Each mismatch needs an explicit rule — transform, default, or route to a human — written down, because these rules are the business logic of the integration and the thing the next developer needs to read.
Design for failure visibly. Records that cannot sync — validation rejected, API down, mapping rule missing — should land in an error queue a person actually reviews, not vanish into a log. Retries must not create duplicates when the same record arrives twice, and a silence alarm should fire when the pipeline has been quiet longer than normal, because the worst failure mode is the sync that stopped three weeks ago and nobody noticed while the systems drifted apart.
Run the backfill and the ongoing sync as separate jobs: the historical load happens once, in bulk, with its own reconciliation pass — counts and spot-checks on both sides — while the ongoing sync handles the daily trickle. Once live, the payback is typically immediate and measurable: hours of typing gone, and the error class of transposed digits and missed records gone with it.
