Make your systems talk, and tell you when they stop
Your CRM, accounting, calendar, and inbox already hold the data. We connect them properly — with retries when a service goes down, logs of what moved, and an alert the moment something breaks.
Retry queue
Monitoring dashboard
From $1.2k
A system integration connects two or more pieces of business software so data moves between them automatically. Done properly it includes field mapping, data validation, two-way sync with conflict handling, a retry queue for when a service is unavailable, and monitoring that alerts a human when something fails. DAvision builds these in Calgary from $1,200 for a single one-way connector up to $8,500 for a custom middleware layer you own outright.
The copy-paste tax
The same record is entered three times
Once in the CRM, once in accounting, once in the spreadsheet somebody maintains. Two of those will disagree by Friday.
The integration you have breaks quietly
Off-the-shelf connectors fail without telling anyone. By the time the gap is noticed the reconciliation is a day's work.
Nobody knows which system is right
When two records conflict there is no rule for which wins, so the answer is whoever shouted most recently.
How we build connectors
Field mapping agreed up front
Which field goes where, what happens to the ones that do not match, and what a valid value looks like.
Two-way sync with conflict rules
A defined winner for every field when both sides changed. No silent overwrites.
Validation before anything is written
Bad data is rejected at the boundary and reported, rather than propagated into three systems.
Retry queue and event replay
When a service is down the work waits and replays. Failed events can be reprocessed rather than reconstructed by hand.
Monitoring dashboard
What synced, what failed, what is queued — visible without asking us.
Middleware you own
On Enterprise, the integration layer is yours: your repository, your hosting, documented so another team could maintain it.
How it works
Four steps, no surprises. You see a working version before you pay the balance.
Map the data
Which systems, which objects, which direction, and what the rules are when they disagree.
Build the connector
Including validation, retries, and logging from the first version, not added later.
Run in parallel
Sync in read-only mode and compare against the existing manual process until they match.
Cut over and monitor
Live, with alerting and a dashboard your team can read.

Two-way sync is where most integrations quietly go wrong
One-way sync is straightforward: one system is authoritative and the other follows. Two-way is where the difficulty lives, because eventually the same field changes on both sides between syncs and something has to decide which version survives. Most off-the-shelf connectors resolve this with last-write-wins, silently. That is fine until the losing write was a corrected address and the winning one was a stale import.
So conflict rules get agreed before anything is built, field by field. Which system owns the phone number. What happens when the CRM and the accounting package disagree about a company name. Whether a blank value means 'no data' or 'delete what is there' — a distinction that has erased more customer records than any other single cause we encounter.
The second thing to get right is validation at the boundary. A malformed postal code or a negative quantity should be rejected and reported at the point of entry into the integration, not propagated into three downstream systems where someone will find it in a report next quarter. Rejected records go to a queue a human can review, rather than being dropped.
Then there is the parallel run. Before cutover, the integration operates in read-only mode alongside the existing manual process, and we compare outputs until they agree. This is unglamorous and it adds a week, and it is the single most reliable way to avoid the scenario where an integration goes live and quietly corrupts data for a month before anyone notices.
What changes after launch
Concrete, measurable, and checkable against the baseline we take before we start.
One version of each record
Duplicate entry stops, and the disagreements between systems that duplicate entry produced stop with it.
Outages become delays, not losses
The retry queue holds work while a service is down and replays it afterwards.
You can see what moved
A monitoring dashboard showing what synced, what failed, and what is waiting — without asking us.
Who this is for
Clinics syncing practice management with accounting and recall campaigns. Construction firms moving project data into invoicing. Real estate teams connecting listing platforms to CRM. Anyone whose staff are the bridge between two systems that should talk directly.
We work with dental clinics, construction, energy, real estate, and commercial businesses across Calgary and Canada.
Frequently asked questions
How much does a system integration cost?
One connector between two systems, one-way, starts at $1,200. Up to three integrations with two-way sync, conflict handling, retries, and a monitoring dashboard is $3,500. Unlimited integrations on custom middleware you own starts at $8,500.
Which systems can you connect?
Anything with an API or a reachable database. HubSpot, Salesforce, QuickBooks, Xero, Google Workspace, Microsoft 365, Shopify, Stripe, and most industry-specific platforms are routine work.
What happens when one of the services goes down?
The work queues rather than failing. When the service returns, the queue replays. If a failure is genuine rather than transient, you get an alert the same hour.
Can we not just use Zapier?
Sometimes yes, and we will say so. Zapier is a reasonable answer for simple one-way triggers. It struggles with two-way sync, conflict rules, high volume, and anything needing real error recovery.
Who owns the integration?
At Enterprise tier, you do — code in your repository, running on your infrastructure, documented. At Basic and Pro we host and maintain it.
How long does it take?
One to two weeks for a Basic connector, three to four weeks for Pro. Most of the time goes into the parallel-run validation, which is what stops bad data reaching production.
