Running your POS when the internet is down

इन्टरनेट नहुँदा POS कसरी चलाउने

Engineering 20 December 2025 6 min read

Customers don't pause when the internet does. In Nepal, where power cuts and patchy connectivity are a fact of life, a POS that needs the cloud to make a sale is a POS that loses you money. NitiERP is built offline-first.

What "offline-first" actually means

  • The full catalog, prices, taxes and customer balances are stored on the device.
  • Sales, returns and payments are recorded locally and instantly — no spinning loader at checkout.
  • When the connection returns, everything syncs automatically in the background.

How sync stays correct

The hard part isn't going offline — it's coming back without corrupting your data. NitiERP uses a conflict-aware sync:

  • Each transaction carries a device ID and timestamp.
  • The server replays transactions in order and resolves clashes (e.g. the same item sold on two terminals) using deterministic rules.
  • Stock and ledgers end up identical to what they'd be if everything had been online the whole time.

What this means for you

  • Never stop selling during an outage.
  • No double counting when terminals reconnect.
  • Multi-terminal shops stay consistent across counters and the central server.

You shouldn't have to think about any of this — and with NitiERP, you don't.


नेपालीमा

इन्टरनेट रोकिए पनि ग्राहक रोकिँदैनन्। बिजुली जाने र कमजोर कनेक्सन सामान्य भएको नेपालमा, बिक्री गर्न क्लाउड चाहिने POS ले पैसा गुमाउँछ। NitiERP अफलाइन-फर्स्ट बनेको छ।

"अफलाइन-फर्स्ट" को अर्थ के हो

  • पूरै क्याटलग, मूल्य, कर र ग्राहक बाँकी डिभाइसमै राखिन्छ
  • बिक्री, फिर्ती र भुक्तानी स्थानीय रूपमा तुरुन्तै दर्ता हुन्छन् — चेकआउटमा लोडिङ कुर्नु पर्दैन।
  • कनेक्सन आएपछि सबै स्वतः सिङ्क हुन्छ।

सिङ्क कसरी सही रहन्छ

गाह्रो भाग अफलाइन जानु होइन — डाटा नबिगारी फर्किनु हो। NitiERP टकराव-सचेत सिङ्क प्रयोग गर्छ:

  • हरेक कारोबारमा डिभाइस ID र समय हुन्छ।
  • सर्भरले क्रमशः कारोबार पुन:चलाउँछ र टकराव (जस्तै एउटै वस्तु दुई टर्मिनलमा बिक्री) निश्चित नियमले मिलाउँछ।
  • स्टक र लेजर सधैं अनलाइन भएजस्तै मिल्छन्।

तपाईंका लागि यसको अर्थ

  • आउटेजमा पनि बिक्री कहिल्यै रोकिँदैन
  • टर्मिनल फेरि जोडिँदा दोहोरो गणना हुँदैन
  • बहु-टर्मिनल पसल काउन्टर र केन्द्रीय सर्भरमा एकरूप रहन्छ।

यी कुरा तपाईंले सोच्नै पर्दैन — NitiERP सँग, पर्दैन।
