What should go into the extra-cost budget?
The platform subscription and the running cost are different lines in your budget. HighLevel’s billing guide describes metered services, wallet charges and optional products. Enter your expected combined amount in “Usage & add-ons” above. The calculator does not infer it from your number of clients.
| Cost bucket | What to check before buying |
|---|---|
| Communication usage | Expected email, SMS and call volume; phone numbers and destination-specific rates. |
| Optional products | Any AI, hosting, branded app or other add-on your offer depends on; confirm its billing unit. |
| Software you keep | Existing accounting, analytics, specialist integrations or delivery tools still needed after the move. |
| Transition | Import work, workflow rebuilding, team training, contract exit charges and overlapping subscriptions. |
| Cash buffer | Timing of supplier charges versus money actually collected from clients. |
Do not set retained software to zero because two products have similar feature names. List each paid tool, the job it performs and the acceptance test for removing it. Keep its subscription in the estimate until that test passes. If usage varies sharply between clients, model a busy month as well as an ordinary month.
A worked example: ten client workspaces
Suppose an agency spends $1,250 a month now. It expects $150 in monthly usage and extras, $100 in retained software, $1,500 of migration work and one month paying the old stack during the move. These are illustrative inputs, not measured customer results.
| Budget | Unlimited billed monthly | Unlimited billed annually |
|---|---|---|
| Base subscription over 12 months | $3,564 | $2,970 |
| Usage and retained tools over 12 months | $3,000 | $3,000 |
| Migration plus overlap | $2,750 | $2,750 |
| First-year total | $9,314 | $8,720 |
| Difference from the $15,000 old stack | $5,686 lower | $6,280 lower |
The annual option changes the base fee by $594 in this example. It does not remove migration work or usage. If the old stack costs less than the new total, the calculator shows an extra cost rather than describing the move as a saving. The estimate excludes tax and foreign exchange.
Monthly or annual: compare the commitment as well
Annual billing pays the base subscription upfront. Dividing that payment by twelve is useful for comparison, but it is not an instalment offer. Compare the cash you must commit now, the length of your client contracts and how thoroughly you have validated the platform.
A base-fee comparison reaches the annual price after ten monthly payments at the displayed rates. That arithmetic is not a refund policy. Check the vendor’s cancellation and renewal terms, especially if you may change tiers or stop using the software within the year.
Start by testing one representative workflow with the people who will use it. Record the test result before committing a full client portfolio. If you already know you need SaaS Mode, assess its configuration and billing flow specifically; client count alone is not a reason to pay for Pro.
Compare Unlimited and Agency Pro in detail →Questions to resolve before choosing
Does “Unlimited” mean every charge is included?
No. Treat account capacity separately from metered services and optional products. Get a usage estimate for the services you intend to enable and include it in the calculator.
Is Agency Pro necessary for more clients?
Unlimited already provides unlimited sub-accounts. Pro is a feature decision: check SaaS Mode, markup rebilling and advanced API requirements against the current plan comparison.
Can I count money billed to clients as a cost reduction?
This calculator compares software spending, not your agency’s revenue. Keep client receipts in a separate cash-flow model, including failed payments and your support costs. A charge raised is not the same as cash collected.
When should I keep my existing software?
Keep it if the required workflow, data access or reporting cannot be reproduced at an acceptable cost. Run a narrow pilot first and price a partial move rather than assuming you must replace everything.
