Billing software or a WMS?

A warehouse management system runs the floor: where things go, what to pick, what was scanned. Billing software turns what happened into invoices. WMS products built for 3PLs usually include billing, so the question a small pallet warehouse really faces is whether it needs the rest.

This page compares the two kinds of software, not brands. We make billing software, so read it with that in mind. Where a WMS is the better answer, it says so.

What each one does

Typical capabilities. Individual products differ, so check the ones you look at.
	Warehouse management system	Billing software (such as Tallybay)
Where each pallet is: aisle, bay, level	Yes, by location	No
Directs picking and put-away	Yes	No
Barcode or RF scanning	Usually required	Not needed
Inventory by item, lot or expiry date	Yes	No: pallets per client
Client portal, advance ship notices, EDI	Often	No
Storage, handling and service billing	Often a module	The whole point
Evidence behind every invoice line	Varies	Yes
Change how the crew works	Yes: devices, locations, training	No
Time to start	Setup of locations, items and devices	Rates and an opening balance

Billing software is probably enough when

Goods come in and go out as whole pallets, not picked by the case or the each.
Your crew already knows where each client's pallets are, because the building is small enough.
Clients don't need to see live inventory online or send you orders by EDI.
You don't track lots or expiry dates for anyone.
The pain is at month-end: invoices rebuilt from spreadsheets, charges missed, clients asking why a number is what it is.

In that case a WMS mostly adds devices, setup and training to solve problems you don't have, and billing is the part you actually needed.

You probably need a WMS when

You pick and pack orders, by the case or the each, rather than moving whole pallets.
You must trace lots or expiry dates, as with food, beverage or pharmaceuticals.
Clients store many different items and you need to find one fast.
Clients require a portal, advance ship notices or EDI.
Mistakes on the floor, not on the invoice, are what cost you.
You run several buildings and need one view of where everything is.

If that is you, buy a WMS with billing built in. Tallybay does not track locations, items or lots, and it will not grow into a WMS.

What you give up either way

Choosing billing software

No record of where a pallet sits, and no scanning that directs put-away or picking. A pallet tag can be written onto an entry as a note; it is not a location.
Inventory is a pallet count per client, not a list of items.
Someone enters receipts and shipments, from a phone or a spreadsheet import.
No client portal.

Choosing a WMS

Setup: locations, items and devices have to exist before it works.
The crew changes how they receive and ship, and needs training and hardware.
You pay for running the whole floor, not just for the invoices.
Billing is one module among many, so check its storage rules as carefully as its scanning.

Questions to ask any software that bills storage

Can it bill per pallet per day, and per pallet per month both prorated and in full?
How does it bill a pallet that arrives on the 28th and leaves on the 3rd?
Does it apply free days per receipt, and a minimum monthly charge?
Can it bill half-month or anniversary terms, if your contracts use them?
When a rate changes mid-month, which days get which rate?
Can you see which receipts and shipments produced each storage line?
Is a mistake voided and reissued with the history kept, or edited in place?
Can you export everything, and leave, whenever you want?

The guide to billing pallet storage shows what the right answers look like with numbers. Tallybay's own answer to question 4 is no, not yet.

If you might need a WMS later

Starting with billing does not lock you in. Keep your records in a form you can export: Tallybay exports clients, rates, activity and invoices as CSV at any time. The billing rules in your contracts stay the same whichever system applies them.
