About this gig
A customer buys in-store, and your online store still shows it in stock that's a refund or a lost sale happening right now.
Restaurant and retail POS owners lose revenue weekly to broken POS integration. Owners in the US, UK, and Nigeria deploy this to stop losing sales to sync errors.
This transforms fragmented checkout into one connected system that protects every sale.

I help businesses build, customize, and automate their Shopify stores from setup to full operations. My work covers Shopify theme customization, app integrations, POS and inventory sync, payment gateways including Stripe, PayPal, Flutterwave, and Paystack, and workflow automation using n8n, Zapier, and Klaviyo. I also connect Shopify to CRM platforms like HubSpot and Zoho, and to accounting tools like QuickBooks and Xero. Every setup is tested end-to-end before handover.

FAQ
Can you fix Shopify POS inventory that's not syncing with my online store?
Yes. Shopify POS desyncs are usually caused by webhook delays, duplicate SKUs, or wrong location mapping. I check inventory settings, location mapping, and webhook activity, then correct the mismatch so stock matches online and in-store. Most fixes complete same session with Shopify admin access.
Can you fix Square POS payments that aren't going through?
Yes. Square POS payment failures usually trace to a card reader issue, an expired API key, or a conflict with Stripe or PayPal running alongside it. I test the flow end to end reader, gateway settings, transaction logs, and resolve the exact error code you're seeing.
Can you fix Toast POS freezing during checkout?
Yes. Toast POS freezing is usually caused by a corrupted menu sync, an outdated Toast Tab version, or a conflict with a third-party ordering integration. I review your menu, modifiers, and integrations to isolate the trigger, then rebuild the affected section.
Do you work with Clover POS and Lightspeed POS?
Yes. I set up, configure, and troubleshoot Clover POS and Lightspeed POS, inventory sync, hardware pairing for printers and card readers, and gateway configuration. Same process used for Square and Toast, so any combination runs as one connected project.
Can you connect my POS to WooCommerce or Odoo?
Yes. I connect POS systems to WooCommerce for real-time inventory and order sync, and set up Odoo 17 POS and ERP modules for businesses needing accounting, inventory, and POS in one system. Both handled as part of your integration.
Can you also set up QuickBooks or Xero accounting sync?
Yes. I connect QuickBooks Online or Xero to your POS so sales, refunds, and inventory costs post automatically instead of manual entry. Included in Global Command Center, or as an add-on to Connected Checkout. Zapier connects platforms without native support.
