1LINK has welcomed Sindh Bank Limited as a Reverse Bill Aggregator on its 1BILL payment platform, enabling customers of sub-billers operating under corporate arrangements with the bank to make invoice and voucher payments through participating financial institutions. The development expands the range of payment services available through 1BILL and provides an additional collection channel for businesses and organisations associated with Sindh Bank. According to the announcement, customers can now settle their payments through mobile banking, internet banking, automated teller machines (ATMs) and over-the-counter (OTC) channels offered by 1LINK member institutions. The arrangement is intended to make bill settlement more accessible by allowing customers to use existing banking channels rather than depending solely on the payment methods traditionally provided by individual service providers. As a Reverse Bill Aggregator, Sindh Bank will facilitate the collection of payments for its associated sub-billers through the 1BILL network. The announcement identifies the service as an invoice and voucher payment facility, extending the bank’s role in connecting corporate payment collections with Pakistan’s interoperable financial infrastructure.
Under the announced arrangement, customers of eligible sub-billers can use the 1BILL payment option through the available channels of participating 1LINK members. The payment process requires users to enter the designated 1BILL prefix before their registration number so that the relevant invoice or voucher can be identified. The promotional material shared by 1LINK specifies the invoice prefix as 105198. Customers will therefore need to follow the prescribed format when entering their payment reference to retrieve the relevant bill information. The available channels include mobile applications and internet banking services, allowing customers to complete transactions digitally, as well as ATMs and OTC facilities for those who prefer assisted or physical banking channels. This multi-channel arrangement can be useful for businesses serving customers with different levels of access to digital banking. It also gives customers the flexibility to choose a payment method based on their banking preferences and available services. However, the announcement does not provide a list of the individual sub-billers covered under the arrangement, so customers will need to confirm whether their particular service provider is included before making a payment through the new option.
The onboarding adds another banking institution to the growing network of organisations using 1BILL for invoice and voucher collections. The platform connects billers with participating banks and payment channels, allowing customers to settle different types of obligations through established financial infrastructure. Reverse bill aggregation is particularly relevant for organisations that operate through corporate or institutional arrangements and need a mechanism to collect payments from their customers. Instead of requiring every sub-biller to establish separate payment arrangements with multiple banks, an aggregator can facilitate access to a wider payment network through a common infrastructure. For participating businesses, this can provide a more centralized collection route, while customers benefit from the ability to make payments through banking channels they already use. The addition of Sindh Bank is therefore relevant to the expansion of 1BILL’s institutional and corporate payment network. It also follows other developments involving 1LINK’s bill-payment ecosystem, including the onboarding of financial services organisations and the introduction of services designed to bring multiple billers together through participating banking applications. The specific operational arrangements and settlement procedures for Sindh Bank’s newly announced integration have not been disclosed.
Further details about the arrangement, including the number of participating sub-billers, transaction limits, applicable fees, settlement timelines and customer support procedures, have not been provided. The announcement also does not specify whether additional corporate clients will be onboarded under the arrangement or whether the service will be expanded to include other payment categories. Customers should use the designated prefix and registration number format and verify the displayed invoice information before confirming a transaction. For Sindh Bank and its associated corporate clients, the integration provides access to a wider network of payment channels through 1LINK’s existing infrastructure. For 1LINK, it represents another addition to the organisations using 1BILL to facilitate digital and assisted payment collections. As more banks and service providers connect to shared payment networks, customers can gain additional ways to settle invoices and vouchers through familiar financial channels. The latest onboarding further extends the reach of 1BILL for corporate payment collections, although the broader impact will depend on the range of sub-billers using the facility and the extent to which customers adopt the available payment options.
