To evaluate scheduling software for a staffing agency, test six things: how it fills open shifts, whether it enforces credentials at assignment, how it captures time, how it prices pay and bill rates, how it connects to your ATS and payroll, and what it shows you afterward. Then test the vendor, because you will be iterating with them for years.

Why does generic scheduling software fall short for staffing agencies?

Most scheduling tools are built for an employer scheduling its own employees at its own locations. One workforce, one set of rules, one payroll.

An agency has none of that simplicity. Workers are placed at many clients. Every client has its own sites, its own credential requirements, its own bill rates, and often its own way of approving hours. The record of who was placed lives in an ATS. The money ends up in a payroll system and on an invoice. The schedule sits in the middle office, between all of them.

So the first filter is simple. Ask whether the product was designed for one employer or for an agency with many clients. A tool that cannot hold a different rate card and a different credential list for each client site is going to be worked around with spreadsheets within a month.

What should you work out before you see a demo?

Your own map. You can do it in about two weeks with no vendor involved.

Talk to the people holding the schedule together. Ask them to walk you through yesterday, not to tell you what is wrong. What did they touch by hand? What do they double-check every time because they have been burned? What spreadsheet exists that IT does not know about?

Then trace one placement type from placement to invoice. Every place a person re-keys, re-checks, or reconciles is a requirement. Rank those by how much they hurt. That ranked list is your evaluation criteria, and it is worth more than any feature matrix a vendor hands you. If a vendor offers to run this diagnosis for you, remember that you would be buying their map of your operation.

What should the software actually do?

1. How does it fill an open shift?

  • Does it screen for hard requirements first, such as certifications, schedule conflicts, and approved time off, before ranking anyone? That is a qualification gate.
  • Can you tune how workers are ranked, or is the order fixed?
  • Do workers accept and decline on their phones?
  • What happens when an offer is declined or expires? Who decides the next step, the system or a coordinator?
  • What happens to a shift that is still open an hour before it starts?

2. Does it enforce credentials, or only track them?

  • Is the check automatic at the moment of assignment, or a report someone has to read?
  • Is it made against the date of the shift or against today?
  • Does it also run on shift pickups and swaps?
  • Are requirements set per job?
  • When someone overrides a block, is the reason recorded?

This is the difference between tracking and enforcement, and it is covered in depth in how agencies stop scheduling on lapsed credentials.

3. How does it capture time?

  • Is mobile clock-in tied to a geofence, and is a punch outside it rejected or merely flagged?
  • What happens when a worker has no signal?
  • Is there a path for paper timesheets, and who types them in?
  • Can a worker report missed time after the fact, and who approves it?
  • Can the client approve hours, and is there a signature?

4. How does it handle pay and bill rates?

  • Are bill rates and pay rates separate, per client, site, and job?
  • Are rate changes effective-dated, so old shifts keep old rates?
  • Does it know daily overtime rules where they apply, not just the weekly 40?
  • Are on-call and callback separate categories?
  • What happens to a shift with no rate? It should be flagged, never priced at zero.

The mechanics are in the rate cards piece.

5. How does it connect to your ATS and payroll?

  • Which records sync, and in which direction? Ask for the list.
  • For Bullhorn, at which level do shifts land: job, placement, or both?
  • Is data pushed as it happens or on a schedule?
  • How do approved hours reach payroll? A file export is a fair answer. "It just works" is not.

Be wary of a logo wall. Ask which integrations are live for a customer today and which are planned.

6. What does it tell you afterward?

  • Fill rate and time to fill, by site and job.
  • Shifts you had demand for and never filled.
  • Shifts that were booked and then lost to cancellations and no-shows.
  • Whether you can get the data out.

Which questions separate a partner from a demo?

There is no clean go-live in this layer. Real documents and real workflows expose assumptions a demo never met. So the evaluation question changes. You are not choosing the product with the best week-one demo. You are choosing who you will be iterating with.

Five questions do most of the work:

  1. "Walk me through your worst deployment week, and what you did." A demo has never had one. A partner has stories.
  2. "When something breaks in week two, what is your fix loop, and how fast?" Days is a partner. A quarterly release cycle is a product you will abandon.
  3. "What is adjacent to this workflow, and how do you meet it later?" A point solution ends at its own edges. A partner understands the layer.
  4. "What will this require from our process and our people?" A demo says "nothing, it just works." A partner tells you the truth: ownership clarity, process change, more testing than you expected.
  5. "Show me how the product changed because of a customer." Adaptability is not a feature claim. It is a track record.

A good answer is specific, dated, and slightly unflattering. For a sense of scale, in one of our deployments a client raised 7 issues on a Thursday at 2pm and all 7 were in production before 7am on Friday. Ask every vendor, including us, for their equivalent.

Ask the reference too. Not "are you happy." Ask what they raised last month and what happened to it.

What are the common traps?

Judging on week one. Something will break in week one. That is normal and not a verdict. Judge the tool on week one and you will abandon exactly the deployments that were about to work.

Buying the front office again. Recruiting tools demo beautifully. If your pain is between placement and payroll, another recruiting feature will not touch it.

Digitizing the form. The first generation of tools in this layer made the paper electronic and called it transformation. The work stayed the same. It just happened in a browser. Ask what steps disappear, not what screens replace them.

Waiting for a finished product. Fixing one workflow makes the next one visible. That is the layer working as designed, not scope creep.

Where does Mach 1 fit?

Mach 1 is built for agencies and multi-site operators, and it covers the six areas above: Scheduling & Shift Management, Workforce & Compliance, Time, Rates & Billing, Analytics & Revenue Intelligence, and Sync for paper. It does not replace your ATS or your payroll provider. It is also not an instant switch, and we will tell you that in the first call. The comparison with spreadsheets is a fair place to check whether you need it yet.
