PurposeThe purpose of this study is twofold: to examine the effect of information sharing and contract on increasing the trust level in the relationship between the batik small- and medium-size enterprises (SMEs) and supplier and to examine the trust on performance of a supply chain related to the procurement of raw cotton fabric (mori).Design/methodology/approachThis research used primary data collected through interviews and closed questionnaires using a five-point Likert scale. The sample included 65 people, including batik SME-owners in Pekalongan, a Central Java city. This research was conducted using partial least square (PLS) through SmartPLS 3.0 software to analyze the hypothesis.FindingsThe results of hypothesis testing indicate that trust between owners of SME and their suppliers has a significant positive effect on the performance of supply chain management (SCM). Strong trust between batik SME- owners with their suppliers will be beneficial for both parties. Among other things, trust can reduce unnecessary cost and activity, reduce the waiting time for the arrival of raw material, reduce the number of inventories and increase profit and customer satisfaction. This result has also show that information sharing and informal contract have a significant positive effect on trust between batik SME-owners and their mori suppliers. In this case, information sharing has a higher effect on trust compared to informal contract. Broader information was distributed to the batik SME-owners and their suppliers, resulting in stronger trust between them.Research limitations/implicationsThe limitations of this study include the relatively small sample size and data collection method used to determine the effect of trust, the number of the antecedent variables of trust and the type of scale used to measure the performance of the supply chain. Suggestions for future research may include expanding the scope of the data collection to other regions in Indonesia; adopting a dyadic approach and longitudinal research in providing evidence on the effect of trust as a component of an interactive activity along the supply chain; adding other variables that contribute towards increasing the trust between SMEs and their suppliers (such as commitment); and enhancing the performance measurement of SCM by using a direct measure of financial and non-financial performance instead of recording the perception of the batik SME-owners.Practical implicationsAs the scale of their business increases, it is better if the batik SMEs can enhance information sharing and informal contract with suppliers to promote the development of trust. In this case, to ensure that batik SMEs will have better information sharing from their supplier, it is better if the batik SME-owners using the criteria of supplier willingness to share detailed information when they select the new supplier. Then, to increase the role of contract on trust, it is better if owner of batik SME learn to understand the written contract processes and procedures as their business scale increases.Social implicationsThe research confirms that information sharing, informal contract and trust between batik SMEs and their suppliers can have a positive effect on the performance of the supply chain. It may encourage more SMEs and suppliers in the batik industry to build better information sharing, informal contract and trust as a bottom line for the economic and non-economic growth of their business.Originality/valueThe conceptual model used in this study is original, built from past research about the relationship between information sharing, informal contract and trust on the performance of the supply chain. Besides, the selection of the sample is also original, which in this case is on the batik SMEs which have informal contracts. This case has still been rarely studied, and the research is therefore highly valuable.
