When you’re planning a trip, two airlines might both offer to get you to the same destination. One flies nonstop and gets you there before lunch; the other has you changing planes twice and arriving late that evening. Both airlines keep their promise. But an afternoon enjoying your trip feels very different from an afternoon waiting at another gate.

You can run into much the same thing with payroll integrations. One connection might send payroll information straight to your accounting software when payroll finishes. Another might require you to download a file, sign in to accounting, and import it yourself. Both can get the information where it needs to go. What matters to you is whether it arrives when you need it, includes the detail you rely on, and saves you enough trouble to be worth having.

What work will it actually take off your hands?

A payroll integration moves information between payroll and another system. Whether it helps depends on how much of your work it handles for you. The part it automates may be only one step in a longer routine.

Suppose you’re tired of entering the same hours in timekeeping and payroll. A connection that sends approved hours to payroll could spare you that second round of typing. But if a manager still has to fix missed punches, check overtime, and approve the hours, those jobs remain. If you spend payroll morning chasing approvals, automating the transfer alone won’t get those approvals in any earlier. It may still save useful time; just be clear about which problem it solves.

Timing deserves the same attention. Say you finish payroll at noon and need the accounting entry that afternoon. A connection that sends it overnight could work perfectly and still keep you waiting. Ask what starts the transfer and when the information will be ready in the other system. If you have to press a button to get it moving, that’s still a step to count when you’re comparing the options.

A file import can be a perfectly sensible choice, too. Downloading and uploading a file once a month may be a small price for avoiding a lot of typing. Doing it several times during every payroll is a different proposition. Let the seller walk you through the steps so you can judge the effort for yourself. The software needs to earn its place in your routine by making that routine easier.

The setup matters as much as the connection

An integration can keep repeating a mistake made during setup. If information is matched to the wrong place, every transfer can leave you with another batch of records to fix. You’ll want to know who checks those choices before you start relying on the integration.

Mapping means matching information in one system to the right fields or categories in another. That can involve employee details, pay types, benefit deductions, or accounting entries. General ledger (GL) mapping is the accounting example: matching payroll items to the accounts where they belong in your books.

Let’s say you own a restaurant, and wages are mapped to the account you use for supplies. Your payroll total may be right, but your books will show too much spent on supplies and too little on wages. If nobody catches the mistake, each payday can add more entries for you or your bookkeeper to straighten out.

A file import needs its mapping checked, too. Intuit’s journal-entry import instructions, for example, include matching spreadsheet columns to fields in the accounting software, then importing and checking the entries. The method can change; the need to get those matches right remains.

What does a two-way integration actually cover?

Let’s say an employee changes their address in the benefits system, and you expect payroll to pick it up. If you still have to enter the address in payroll yourself, that’s work the integration hasn’t taken off your hands. Before choosing a provider, you’ll want to know which updates carry over and which you’ll still make separately.

A one-way integration sends information from one system to another. A two-way, or bidirectional, integration sends information in both directions. Those labels describe direction; they don’t tell you whether an address change, a benefit election, or another update is included.

You may also hear 180° and 360°. For example, integration vendor Custom Interface Company uses 180° for one-way payroll/benefits connections and 360° for two-way connections. Whatever label the seller uses, ask which information moves both ways, which moves only one way, and which you’ll need to update separately. That breakdown tells you more about the work you’ll save than the label alone.

You also need to know which system is the source of truth for each kind of information—the one whose record the other system should follow. If the systems disagree, the provider should be able to explain where a correction belongs and how the other record gets updated. Having two places to edit the same record is less helpful than knowing which one to use.

How will you know it worked?

Just because you didn’t get an error message doesn’t mean the integration did its job. When you’re comparing providers, ask how you’ll confirm that the information arrived and is correct. For a timekeeping integration, that could mean comparing the approved hours with what shows up in payroll. You’ll want to know how much of that checking the software handles and how much falls to you.

For example, suppose the payroll costs for two locations arrive in accounting, but all the expense is assigned to one location. The company total could be right while both location reports are wrong. Comparing the total alone would miss the problem. A check of each location’s costs against the payroll records for that period can reveal the mistake.

The provider should be able to show how that comparison works during an ordinary payroll run and explain when it happens. If the checking falls to you or your bookkeeper, that’s time to count when judging how much work the integration saves. An answer about automatic error alerts doesn’t settle who checks the results.

Who will help when something goes wrong?

When an integration goes wrong, you need more than a phone number. Find out who will investigate the problem, arrange the correction, and stay involved until the records are right. Those responsibilities matter even more when payroll and the connected software come from different companies.

Suppose payroll support says the problem is on the accounting side, while accounting support sends you back to payroll. You could spend the afternoon gathering screenshots and explaining the same issue twice, with neither company taking charge of the repair. Before signing, ask who coordinates between them and what happens if your first contact can’t resolve it. If that job falls to you, you should know it while you’re still comparing providers.

Delays in finding a problem can add to the cleanup. Imagine discovering several payrolls’ worth of incorrect accounting entries while the next payroll is already due. You or your bookkeeper could be sorting out which periods need fixing while new entries continue to arrive. If fixing those older entries changes the balances you’re using now, ask who will check that the updated balances are right.

Keep the sales conversation practical: who investigates missing or incorrect information, who fixes it, and who checks the result? If the answer is “we can send it again,” find out who confirms that the resend leaves the records correct. This is where your choice of payroll support model can make a difference to the work you keep.

The arrangement needs to cover later changes, too. For instance, if your accountant reorganizes expense accounts, the GL mapping may need updating. Find out whether help with those updates is included in the service, or whether you would need to arrange it yourself. You don’t want to discover that an account change needed attention after several payrolls have gone to the wrong place.

Is it worth it?

Before an integration becomes a reason to choose one payroll provider over another, you’ll want to know what it takes to get it running and what you’ll pay. Ask how it’s charged: it might be included at no extra charge, need a subscription, or carry a fee each time you run payroll. There may be a one-time setup fee as well.

Even an integration that’s free to use can take time to set up. The provider should explain what it will handle, what it expects from you, and how much time to allow. If you’ll need your bookkeeper or someone else to help, count their time and any fee they’ll charge, too.

Get the charges in writing, including setup, ongoing use, later changes, and help fixing problems. Find out how any fees are calculated and who bills you, including whether you’ll need a separate connector or software subscription. You should be able to explain what you’ll pay for without piecing it together from several conversations.

The effort doesn’t end with setup. Try getting to the connected task as part of the demo. Can you open it from payroll, or do you need a separate application and another sign-in? Single sign-on, or SSO, lets you sign in once to reach multiple applications, as Microsoft’s explanation describes. That can make access easier, but it doesn’t tell you which payroll information transfers.

An extra login once a month might not bother you. Repeating it throughout every payroll could become an irritation you wish you’d noticed sooner. Have whoever will use the connection try it with the access they’ll receive. Find out how someone else could get the right access when the usual person is away.

Give it a five-minute test in the demo

Use five minutes of the demonstration to follow one job you want the integration to make easier. Bring the report or result you need and a short list of the steps you take now. You’ll have something concrete to compare with the seller’s demonstration.

Ask to see three things:

  1. The information you need, in the place you’ll use it. Look at what moves, the detail it includes, and where you would make a correction. Find out which updates move both ways, which move only one way, and which you would still need to enter separately.
  2. The steps you’ll still have to take. Walk through preparation, approvals, sign-ins, downloads, uploads, and checking where they apply. Find out what starts the transfer and when the information should be ready to use.
  3. A result you can check. Find the transfer confirmation, inspect what arrived, and compare it with the original records and the result you expected.

Five minutes gives you a useful first look; setup validation and unanswered questions still need follow-up. Keep a note of what you saw, what the seller only described, and what remains unclear. Get written answers about setup, help with problems, later changes, and the full price.

Now go back to your list of steps. Cross out the work the demonstration showed you could stop doing, and agree who will handle what remains. If the task you most wanted off your desk is still there, find out what else would be needed to remove it before that integration tips your decision.
