How long should it take to standardize the tech stack across a new bolt-on?

Plan for 6 to 9 months from close to full cutover on the core systems, ATS and back office. Do not rush it into 90 days. The teams are still absorbing new ownership, new comp plans, and new leadership. Stack a full system migration on top of all that and you will lose producers. Sequence it. Stabilize the deal first, then move the systems.

Should we force every acquired brand onto one ATS?

Not always. One ATS is the goal for firms in the same discipline, like light industrial or IT contract. It is not always right when a brand serves a very different market with a specialized workflow the standard platform cannot handle. Pick the system that fits the biggest revenue segment, then test it hard against the outliers before you commit. A forced migration that breaks a niche brand's delivery costs more than running two systems for another year.

What is the single biggest mistake PE portfolios make with tech consolidation?

Moving data before they clean it. Firms migrate years of duplicate candidate records, dead reqs, and broken tags into the new system on day one. Now the new platform is as messy as the old one and nobody trusts the reports. Clean the data at the source before it moves. It is boring work and it saves the whole project.

Standardize Tech Stacks Across Staffing Bolt-Ons

Q1 2026 delivered 35 staffing M&A deals, the strongest opening quarter in three years. PE buyers want tech-enabled platforms and premium multiples. Here is how to standardize fragmented tech stacks across bolt-ons without losing a quarter of revenue.

Q1 2026 closed with 35 staffing M&A deals, the strongest opening quarter in three years. PE buyers are not just buying revenue anymore. They are paying premium multiples for tech-enabled platforms, and they expect the portfolio to look like one company by exit, not five brands taped together.

That expectation lands on the portfolio operations leader. You inherit a founder-built firm running Bullhorn, a bolt-on running JobDiver, a third brand on a homegrown ATS nobody has documented, and three different back-office systems that do not talk to each other. The mandate is clear: standardize the stack, capture the synergies, and do it without stalling revenue.

Most portfolios botch this. They either move too fast and lose producers, or they never move at all and end up carrying five license fees and zero shared data at exit. Here is a repeatable process that avoids both.

Stop treating every deal as a fresh problem

The firms that struggle with integration handle each bolt-on like it has never happened before. They spin up a new project, hire a new consultant, and relearn the same lessons. That is how a 6-month integration turns into 18 months.

Build a standard integration playbook once, then run it every time. The playbook answers the questions you will face on every deal before you close the deal.

What is the standard ATS for each staffing discipline in the portfolio?
What is the standard back-office and pay-bill system?
What is the standard CRM and who owns the data model?
What order do we migrate systems in, and what is the trigger to start each one?
Who on the acquired team owns the cutover on their side?

Write those answers down. Now every new deal starts at step 40, not step one. The first bolt-on takes 9 months. The fourth takes 4.

Sequence the migration so revenue keeps moving

The mistake that kills momentum is trying to migrate everything at once. A staffing firm's revenue runs through the ATS and the pay-bill system every single day. Break either one and you break cash flow.

Migrate in a fixed order and stabilize each layer before you touch the next.

1. Back office and pay-bill first, but quietly

Get the acquired brand onto your general ledger, payroll, and billing platform inside the first 90 days. This is the least visible change to recruiters and the most important for financial reporting. Producers do not care what runs payroll as long as candidates get paid on time. Do this early and clean.

2. ATS and candidate data next

This is the system your recruiters live in, so it needs the most care. Do not migrate on a Friday and expect people to figure it out Monday. Clean the data at the source first. Kill the duplicate candidate records, close the dead reqs, and fix the tags before anything moves. Then run parallel for two weeks with real training and real support, not a recorded video and a prayer.

3. CRM and reporting last

Once the operational systems are stable, unify the CRM and the reporting layer. This is where the portfolio value actually shows up. When every brand feeds one data model, you can compare fill rates, gross margin, and recruiter productivity across the whole platform. That single view is what a buyer pays a premium for at exit.

Protect the producers or lose the deal value

You did not buy the software. You bought the client relationships and the recruiters who own them. A tech migration that annoys your top billers is a bad trade no matter how clean the data model looks.

Three rules keep producers on your side.

Name a local champion. Pick a respected recruiter or manager inside the acquired brand to co-own the cutover. Change forced from the portfolio HQ gets resisted. Change led by a trusted colleague gets adopted.
Migrate their live desks last, not first. Start with a small team or a single office. Prove the process works, fix what breaks, then roll it to the heavy billers once the path is smooth.
Keep the numbers they can see. If your new ATS changes how commission-relevant data gets tracked, show every producer their numbers in the old system and the new system side by side. Recruiters do not trust a platform that might cost them a check. Remove that fear on day one.

The goal is not a perfect system. The goal is a standardized stack that your best people will actually use. A slightly-less-elegant platform that recruiters trust beats a beautiful one they work around.

Know your metrics before you touch anything

You cannot prove the integration worked if you never measured the starting point. Before the first migration, capture the baseline on each brand: fill rate, time to fill, gross margin per placement, recruiter productivity, and days sales outstanding.

Then watch those same numbers through the cutover. A short dip during training is normal. A dip that does not recover after 60 days means something in the new workflow is worse than what you replaced. Catch it early and fix it before it spreads to the next bolt-on.

This is also how you defend the integration budget to the deal team. When you can show fill rate held steady and reporting improved across four brands, the next acquisition's integration gets funded without a fight.

Your move this week

Pull the list of every system running across your portfolio right now. Every ATS, every CRM, every pay-bill and GL platform, by brand. Put it in one spreadsheet with the annual license cost next to each line.

You will almost certainly find duplicate spend and at least one system nobody can fully explain. That spreadsheet is the first page of your integration playbook, and you can build it in an afternoon. Start there.
