Offline and cloud

What works without internet, what needs the shop network, and what the cloud sees

"Works offline" can mean many things. Here is exactly what it means in MartPOS.

The shop's main PC runs the MartPOS store server, which owns that branch's database: stock, bills, khata and the day book. Only the store server writes to it. The till on the same PC, and tills on other PCs in the shop, all ask the store server. Never put the store's database on a shared folder, OneDrive or Google Drive: MartPOS is built on the rule that one program owns it.

A sale is saved on the store PC together with a numbered message for the cloud, in one step. Every 15 seconds (less often while the cloud is not answering), or when you press Sync now, the store sends what is waiting. A message sent twice counts once, and the store forgets a message only after the cloud confirms it has saved it. In a test, sales made while the cloud was switched off reached it later, and the cloud's daily totals matched the store's own report.

The owner portal's dashboard: Main branch (MAIN) marked Recent, Rs 30,721.08 of net sales today from 19 bills and Rs 678,542.76 over the last 7 days from 473 bills, with each day's bills, net sales and returns Open the full-size screenshot

Keeps working

Internet down

Selling, returns, purchases, khata payments, closing a shift and printing all continue. Changes wait on the store PC, in order.

Keeps working

MartPOS Cloud down

The same as no internet. The store retries on its own and never loses what is waiting.

Other tills stop

Shop network down

A till on another PC cannot bill without the store PC. Its bill in progress is kept, and a retry cannot post it twice. The till on the store PC keeps working.

Shop stops billing

Store PC off

Every till needs it. No second PC quietly takes over, because two PCs selling the same stock separately could both sell the last packet.

Offline and cloud

What the owner sees online

Daily sales per branch

Sales and returns per day as each branch reported them, in rupees, with the time of its last report.

Stock, khata and more, read-only

Each branch's stock (also per place), purchases, customer and purchase orders, khata and advances, expenses, shifts, staff, alerts and a sales report, as its store PC last sent them.

STALE, never "live"

A branch that has not reported for 15 minutes is marked STALE, because it may be selling right now without the internet.

Paired PCs

Store PCs with their last-seen time and licence grant. Revoke one and its cloud access stops at once.

Items, prices and settings

Add items, or change an item's name, packs, barcodes, prices or tax, and some shop settings; each branch applies them at its next sync unless the shop changed that item meanwhile.

Settings for all branches

Share a section of settings, such as the receipt, the ways of paying or the khata rules, from one branch with every branch that follows. Each store PC applies it with its own checks, and the portal shows what each branch did with it.

Branch transfers

Goods sent between branches as the cloud relayed them: on their way, received in full or short.

Managers, by branch

An owner invites managers by email to see the records and alerts, for every branch or only chosen ones. A manager changes nothing on a store PC, the plan or the members.

Two-step sign-in

Owners and managers can require a code from an authenticator app, with one-time recovery codes.

The licence, offline

Signed, checked on the PC itself

A signed grant

The cloud gives each paired store PC a signed grant (30 days by default, then 14 days' grace). The PC checks the signature itself, without the internet.

Clock turned back?

Turning the PC's clock back does not extend a grant. A suspension is only noticed at the next check-in.

Backups

The store PC takes an encrypted backup at the time you choose, after each shift closes and before each database upgrade, reads it back to check it, and can keep a second copy in another folder such as a USB drive. An owner can restore one on screen, on the same PC or a replacement.

Common Questions

Offline & Cloud — FAQs

Nothing changes at the counter. The shop keeps billing, and changes go to the cloud, in order and each once, when the internet returns.

Yes, each branch's daily sales in the owner portal, with the time the branch last reported. If a branch has not reported for 15 minutes it is marked STALE, never shown as live.

Tills on other PCs cannot bill until it is back; their open bills are kept. MartPOS deliberately does not let a second PC take over the stock.

No. Each store PC holds a signed grant it checks itself, valid for 30 days by default plus 14 days' grace, renewed whenever it syncs.

No. One program, the store server, must own the database on the store PC's own disk. A synced or shared folder can corrupt it. For a copy away from the PC, set a second backup folder, such as a USB drive, in Settings › Backups.

Yes. On the Sync & FBR page, Pause sync stops sending until someone resumes it; billing and the licence check carry on, and records wait on the store PC. Unpair, after typing UNPAIR, removes the PC's cloud credentials and keeps all its data; it is refused while records are still waiting to be sent.

The bill in progress is kept on the PC and comes back when MartPOS starts again. A sale retried after an unclear answer cannot be posted twice. Billing needs the store PC to be on, so a UPS on the store PC helps during load-shedding.
