Common questions

Yes. For Singapore businesses, OPSYNC generates Peppol BIS Billing 3.0 XML — the format required by IRAS for InvoiceNow submission. The system auto-detects whether your invoice qualifies as a simplified tax invoice (under S$1,000) or a full tax invoice, and applies the correct GST categories (standard-rated, zero-rated, exempt). Live submission via an IMDA-accredited Peppol Access Point is on our roadmap — you can download the XML and submit via your Access Point today.
Yes. When your business is mandated by LHDN to submit e-Invoices (typically once annual turnover exceeds RM1 million), you enable compliance in Settings and OPSYNC generates UBL 2.1 XML for you to upload to the MyInvois portal at mytax.hasil.gov.my. You then paste back the UIN once LHDN validates it. Businesses not yet mandated can continue issuing invoices as normal. e-Invoice compliance is available on the Growth plan and above.
OPSYNC supports all three IRAS GST categories: Standard-Rated (9%), Zero-Rated (0%), and Exempt. Select the GST category per invoice when creating or editing. The GST F5 report (in Reports → GST F5) automatically calculates Boxes 1–7 based on your invoices and purchase records for the selected period.
Yes. Invoicing, quotations, CRM, expenses, purchasing, stock, sales orders and reporting all work the same for businesses anywhere, billed in your own currency. e-Invoice compliance (Peppol InvoiceNow and LHDN MyInvois) is specific to Singapore and Malaysia's tax authorities, so that particular feature is only available to businesses registered in those two markets — everything else is fully available regardless of where you're based.
No. OPSYNC is designed for business owners and operations teams, not accountants. The interface is straightforward — create an invoice, send it to your client, record payment. Reports are generated automatically.
No catch. The Trial plan gives you full access to all features for 14 days — no credit card required. After 14 days, your account moves to the free tier: 1 user, 10 invoices/month, 10 quotes/month, up to 20 clients. Your data is always preserved. Upgrade anytime to a paid plan to restore full access.
It depends on your plan — Trial (free tier) supports 1 user, Starter up to 3, Growth up to 8, Pro up to 20, and Enterprise is unlimited. To increase your seat limit, contact us to upgrade your plan.
OPSYNC has 7 built-in roles: Admin (full access to own org), Manager (all modules except Team and Settings), Sales (Leads, Quotes, Sales Orders, Invoices, Clients, Expenses), Purchaser (Requisitions, Purchase Orders, Suppliers, Products, Expenses), Finance (Invoices, AP Purchases, Payments, Reconciliation, Reports, Export), Store (Products, Delivery Orders, Purchase Orders view, Service Reports, Requisitions) and User (Dashboard, Requisitions, Expenses, Projects, Support). Admins can further fine-tune which modules each role sees via Settings → Roles & Permissions — a click-to-cycle matrix with live preview. Action-level guards (such as blocking self-approval of one's own requisition) are hardcoded and cannot be overridden.
Yes. All data is stored with Row-Level Security enforced at the database level — every query is strictly scoped to your organisation. Your data is never shared with or visible to other tenants. All connections are encrypted via TLS 1.2+. Backups run daily. See our Security page for full details.
We issue a subscription invoice by email monthly or annually, depending on your billing cycle. Singapore customers can pay by bank transfer or PayNow. Malaysian customers can pay by bank transfer. Customers elsewhere can pay by international bank transfer — contact us at hello@opsync.digital to arrange payment.
Yes, you can upgrade or downgrade your plan at any time. Upgrades take effect immediately. If you switch to annual billing, you save 20% compared to the monthly rate.
